1 Introduction
Transition metals offer a rich playground for a number of different areas of physics, from basic theory to applications.
Even well-studied compounds that have seemingly simple structure, like the well-known perovskites SrTiO3 and
BaTiO3, still continue to baffle us, both in terms of a theoretical understanding and experimental control over the
structure and properties of these materials. A good example of the challenges presented by oxides in general is
provided by the family of superconducting cuprates. Despite being subjected to an unprecedented level of scrutiny
over the past 20 years, the mechanism of superconductivity still remains unexplained. One of the reasons for these
difficulties is the tight interplay between the electronic structure and minute changes in the crystal structure of
oxides. Due to the compositional complexity, the dominating electronic phase is often determined by the
microstructure of a sample, rather than the structural model that might be inferred from the chemical composition.
Changes in microstructure, such as the formation of nanoscale grains, can alter the lattice spacing, which can alter
metal-oxygen bond angles and defect formation, leading to band structure changes, and ultimately resulting in a
material switching to a different ground state, e.g. an insulator instead of a superconductor, or a ferroelectric instead
of a paraelectric, etc.
The work in this laboratory is directed at achieving a better control over oxides in the form of thin films. The
basic idea is that in oxide heterostructures it is possible to tune one certain characteristic of a crystal more or less
independently from others. We can, for example, change the lattice parameter by epitaxial strain, without changing
the chemical composition. We can also change the density of charge carriers by field effect without altering the
dopant concentration or the structure of a crystal. This approach will, hopefully, allow us to decouple the electronic
and structural aspects of oxides and thus lead to a better understanding of these fascinating materials.
2 Advantages of Thin films
The properties of oxides can be probed in many different types of samples. A common approach is to strive for
perfection in crystal quality and grow the best possible single crystals for detailed characterization. Single crystals,
however, limit us to compositions and structures that are in or at least close to a thermodynamic equilibrium.
A complementary approach is to acknowledge that perfect crystals of complex oxides cannot be grown anyway,
and to deposit thin films instead. Although the crystallinity of films is often lower than that of single crystals, films
do offer a number of additional degrees of freedom for controlling the material properties. The biggest advantage of
thin film growth is that the process is governed by the growth kinetics and it is therefore possible to impose an
artificial nonequilibrium structure on a sample. Simple examples are epitaxial heterostructures, but more complex
lattices can also be grown, e.g. nanostructure arrays, nanoscale composites, and even complete epitaxial device
structures. [1,2]
Another advantage of thin films is the high speed at which samples can be grown. Typical thickness of an oxide
film is measured in tens of nanometers and it is therefore perfectly feasible to grow several crystals in one day.
Integration of many different thin film samples on a single substrate can push this number much higher. [3] This can
be very useful, because it means that we can map the variation of material properties across sections of the phase space.
1
3 Crystal growth
Oxide thin films can be grown by many different techniques. For research purposes, physical vapor techniques like
molecular beam epitaxy (MBE), sputtering, and laser ablation are usually preferred. Among these techniques, laser
ablation, or laser-MBE, is used in our group because it is technically relatively simple yet extremely versatile in
terms of materials and structures that can be grown. We can routinely achieve sub-monolayer deposition rate
control and fabricate samples containing heterostructures, superlattices, nanodots or nanowires.
The largest
challenge is to achieve repeatable and accurate control of crystal composition, defect density, and grain structure.
The usual process parameters that we have at our disposal for controlling crystal growth are the growth
temperature, growth rate, and chemical composition. Composition control can be done at two levels. On a rough
scale, we ensure correct stoichiometry in the film by preparing a deposition target with the desired chemical
composition. This will usually give us films that are within about a tenth of a percent of the desired composition and
therefore possess the crystal structure and electronic phase that we desire.
In many complex oxides, however, this accuracy is not sufficient because we study materials that are close to
electronic phase transitions, where the transport behavior is very sensitive to the density of carriers, or the average
valence state of cations. One such material is SrTiO3, where an insulating parent compound transforms into a
semiconductor, metal, and even a superconductor at doping levels of 1018 to 1020 cm-3. It is thus clear that a much
finer composition control is required than what is easily accessible by simple composition adjustment of deposition
targets.
One way of achieving such control is to utilize the slightly element-selective nature of the laser ablation process.
Specifically, by changing the fluence of the ablation laser, and thus the momentary heating of the evaporation target
surface, we can fine-tune the cation composition in the growing film. This process is illustrated in Fig. 1(a), which
shows a collection of x-ray diffraction patterns from a series of about 50 thin film samples grown at various ablation
laser fluence levels. In all cases, SrTiO3 films were grown homoepitaxially on a SrTiO3 substrate. The substrate
(200) diffraction peak is visible at an angle of 46.5°. It is obvious that the films, despite having the same nominal
composition as the substrate, have significantly different lattice parameters from the substrate. This indicates that
cation nonstoichiometry is present in the films, resulting in lattice parameters that deviate from the bulk value.
Figure 1: (a) X-ray diffraction patterns of a series of homoepitaxial SrTiO3 films, taken in the vicinity of the substrate (200) peak.
The splitting of film peaks from the substrate peak shows that the lattice of the films is larger than in the substrate. (b) The lattice
expansion is a strong function of the ablation laser fluence, and thus the cation stoichiometry. Blue lines are guides for the eye to
illustrate the general tendency.
The deviation of the lattice parameter in the film is plotted as a function of ablation fluence in Fig. 1(b). The plot
shows that below a critical fluence of about 0.3 J/cm2, the lattice quickly expands. Careful analysis of TEM images
has shown that this expansion is caused by the incorporation of extra Sr in the film, i.e. preferential evaporation of Sr
2
from the target at low fluence. At fluence values above 0.3 J/cm2, evaporation favors Ti, and the films thus have a
slight Ti excess. [4] This type of experiment can be used to answer the question of how the electronic properties of
the Sr1+xTi1-xO3 vary as a function of x for small deviations from the ideal stoichiometry.
Stoichiometry deviations obviously result in lattice parameter changes.
The associated vacancies or other
defects can also function as donors for carriers. In systems that are sensitive to small changes in carrier
concentration, this means that composition variations always change both the band filling and the band width. In
thin films, it is possible to decouple these two effects. By using epitaxial strain, we can alter the lattice parameter
without changing the carrier density. In heterostructures, we can introduce carriers by charge transfer or by field
effect, without changing the lattice parameter.
3.1 Strain control
The crystal lattices of many oxides can be viewed as stacks of two or more different types of atomic layers. Thin film
growth offers a way of extending such layering by growing crystals one atomic layer at a time and thus opens a way to
explore the properties of very thin heteroepitaxial layers that can behave quite differently from bulk materials. The
electronic structure of interfacial layers can be influenced by a number of factors, many of which we have
experimental control over. These factors include large compressive or tensile strains of several percent, which would
be unreachable in bulk single crystals. Strain is imposed on thin layers due to a lattice constant mismatch between
materials that are combined. The level of strain can thus be tuned by suitable materials selection or by tuning the
compositions of interface layers. [5,6] Tuning strain in thin films has been shown to affect the type of magnetic
ordering that is observed in manganites, change the critical temperature of high-temperature superconductors, turn
paraelectric titanates into ferroelectrics, and generally affect the easy axis of magnetization and magnetic ordering
temperatures in various oxides. Examples for SrRuO3 behavior under various levels of strain are shown in Fig. 2.

Tensile
Figure 2: The influence of epitaxial strain on the magnetization of SrRuO3. By changing the in-plane lattice parameter of the
substrate, thin layers of SrRuO3 can be grown under compressive strain (green), relaxed state (brown) or under tensile strain
(violet). The easy axis of magnetization can be seen to rotate into the film plane under tensile strain but orient parallel to the
surface normal under compressive strain. Tensile strain also increases the magnetic ordering temperature by about 10%.
3.2 Charge transfer
Another important effect at interfaces is charge transfer between atomic layers. Redistribution of charge across an
interface is a common feature in oxide heterostructures which contain elements that can assume more than one
valence state. Charge redistribution can be directly observed by valence-band photoemission in, e.g. manganite thin
films that are combined in heterostructures with Ti or Fe oxides. Variations of the valence band photoemission
3
spectra of La1-xSrxMnO3 films are shown in Fig. 3 [7,8] The surface layers of thin films can, obviously, be probed
directly by photoemission spectroscopy. The advantage here, compared to bulk crystals, is that reasonably
well-ordered surfaces can be prepared in situ, even for cubic materials that cannot be easily cleaved.
Figure 3: The left panel shows the valence band spectra of La1-xSrxMnO3 for various carrier doping levels x. Spectral feature A
corresponds to the eg levels of Mn, B corresponds to the t2g levels, and C is the O 2p peak. The electron density drops in the eg levels
as the hole doping x increases. In a Mn/Fe heterostructure, the redistribution of charge can be monitored in the Mn oxide layer by
measuring resonant 2p-3d Mn valence band spectra for various thicknesses of the Fe oxide capping layer. Only the eg and t2g spectral
features are visible due to the resonant enhancement of the Mn emission. A cartoon of the measurement is shown on the right.
Measuring the electronic states of buried interfaces layers by photoemission is more difficult, but still possible
when resonant excitation is used. By tuning the x-ray source to the 2p-3d resonance of an element in the buried
layer, the emission intensity from that layer can be greatly enhanced, allowing valence band spectra to be measured
for layers that are covered by a thin cap layer of up to a few unit cell thickness. For the La1-xSrxMnO3 / La1-xSrxFeO3
system, we are therefore interested in the resonant energy of Mn, which is at around 644 eV[9] and of Fe, which is at
around 710 eV.[10] The advantage of resonant spectroscopy is illustrated in Fig.3, where the valence band spectra of
a Mn/Fe heterostructure are shown. A thick La1-xSrxMnO3 film was covered with a thin La1-xSrxFeO3 layer and the
transfer of charge between Mn and Fe was studied. Measurements of samples with a variable cover layer thickness
showed that when La1-xSrxMnO3 is combined with La1-xSrxFeO3, electrons are transferred from the Mn to Fe within a
distance of approximately three unit cells closest to the interface. Effectively, this means that the hole concentration x
is significantly increased close to the interface on the Mn side. Indeed, the change is large enough to destroy the
ferromagnetic phase of La1-xSrxMnO3 within a few unit cells of the interface, which would be bad news if the Mn oxide
were used in a tunnel junction, for example.
While charge transfer at interfaces can be an advantage, in applications it is usually an undesirable effect,
because it means that interface layers behave differently from what one might expect based on bulk material
characterization data. Charge transfer effects often result in thin interfacial layers that are simply called dead
layers and accepted as inevitable, particularly in applications like tunnel junctions. Recent work on measuring the
valence band structure of thin surface and interface layer has opened a new path to correcting such unintended
changes in electronic structure by compensating for charge transfer in each atomic layer by intentionally grading the
chemical composition for each atomic layer in a heterostructure.
3.3 Field effect
The carrier density in an oxide can be modulated by chemical doping and by transfer of charge over short distances at
heterointerfaces.
A third method that can be used to modulate the doping level is field effect.
Field-effect
transistors are arguably the most successful electronic devices ever invented and form the basis for all modern
4
electronics. In oxides, field effect doping of materials offers a way to probe the electronic phase transitions without
creating disorder and lattice parameter changes that inevitably accompanies chemical doping. Field-effect doping
also allows material properties to be modulated repeatedly in a single structure, unlike other doping methods, where
the dopant concentration is fixed during synthesis.
The basic tool of field-effect doping is a field-effect transistor (FET). A number of different device geometries
can be used, but essentially the device has two electrodes, the source and the drain, that feed current into a channel.
The conductivity of the channel is modulated by applying an electric field. The electric field can be applied by
covering the channel with a ferroelectric film, as shown in Fig. 4 (a), or by constructing a parallel-plate capacitor and
applying a bias voltage to the gate electrode, as shown in Fig. 5 (a). The advantage of using a ferroelectric material
as the gate electrode is the ease with which very high electric fields can be obtained, without having to handle the
problem of leak currents and breakdown phenomena that always affect dielectric gate insulator designs.
The
capacitor-type device illustrated in Fig. 5 (a) has the advantage that the gate bias can be changed continuously,
unlike the ferroelectric, which can only be poled to a fixed polarization level of either sign.
The effectiveness of using a ferroelectric film to induce charge at an interface can be seen in Fig. 4 (b).[11] In
this case, a Nb-doped SrTiO3 film was covered with a ferroelectric layer of Pb(Zr,Ti)O3. The slightly underdoped
Nb:SrTiO3 film had a superconducting transition temperature of about 250 mK. The ferroelectric cover layer was
polarized with either a positive or a negative bias of a conducting AFM tip, thereby inducing a charge at the top
surface of the superconducting film.
The P+ polarity corresponds to a reduction of electron density in the
superconductor, while P- corresponds to an increase of carrier density. As a result, the superconducting transition
temperature of the Nb:SrTiO3 film could be shifted by about 50 mK. If the sample temperature is held at 250 mK, it
is possible to switch the film between normal and superconducting states.
An interesting potential application of this technique is the ability to draw superconducting shapes in the film
with an AFM tip. The inset in Fig. 4 (b) shows a line of different polarity drawn on the sample surface. If the polarity
is selected so that the red line corresponds to normal state, the structure could function as a Josephson junction.
Drawing more complex shapes, like nanoscale dot or wire arrays would also be possible. The AFM can be used to
erase and rewrite different patterns in the same sample.
Figure 4: A Hall bar field-effect device (a), consisting of a superconducting Nb-doped SrTiO3 film and a ferroelectric Pb(Zr,Ti)O3 cap
layer. The ferroelectric can be poled with a conducting AFM tip, inducing local shifts of the superconducting transition temperature (b).
A more traditional top-gate field effect transistor (FET) can be used to continuously vary the carrier density in
the channel layer. Our current work is focused on using intrinsic SrTiO3 substrates as the channel of the FET.
Source and drain electrodes are patterned in the substrate surface and an epitaxial or amorphous gate insulator is
deposited. The usual choice for the insulator layer in our devices is either CaHfO3 or DyScO3. Both materials are
wide-gap insulators with low leak currents. A gate field of up to about 8 MV/cm can be applied to the gate electrode,
5
corresponding to a sheet carrier density of 5×1013 cm-2. Assuming a channel layer thickness of 10 nm, the carrier
density induced by field effect in the active region of the transistor can be in the range of 1019 cm-3, which covers the
region where an insulator-metal transition occurs in SrTiO3.
This transition can indeed be seen in SrTiO3 devices, as shown in Fig. 5 (b). The crossover from an insulating
into metallic state occurs at a critical gate bias of 1.3 V. All the gate bias curves cross at a single point at this bias.
The transition from insulating to metallic state is even more obvious in a temperature dependence plot of the channel
current, shown in Fig. 5 (c). The behavior of the device can be understood if we assume that the Fermi level of
undoped SrTiO3 is close enough to the conduction band bottom for carriers to be thermally excited to the conduction
band. Due to the low density of in-gap states, even a fairly small field-induced sheet carrier density can push the
chemical potential in SrTiO3 higher, until it reaches the band edge and the devices switches to a metallic state.
While the temperature dependence of channel conductivity has a thermally-activated shape in the insulating state
and a negative slope in the metallic state, the critical bias value is determined only by the distance of the Fermi level
from the band bottom and is thus independent of temperature.
Figure 5: The basic top-gate field-effect transistor structure (a) using SrTiO3 as the substrate and channel material, metallic LaTiO3
/ SrTiO3 films as source and drain electrodes, and CaHfO3 as the gate insulator. The insulator consists of a thin epitaxial layer and
an amorphous cover layer. An insulator – metal transition occurs at a gate bias of 1.3 V (b). The temperature dependence of
channel current at various gate bias levels clearly shows the transition to metallic state when the gate bias exceeds 1.3 V (c).
4 Conclusion
Thin films, combined with fairly simple device fabrication tools, offer an interesting way to probe phase transitions in
complex oxides.
The active region that is probed by transport measurements in strained heterostructures or
field-effect devices is usually very thin, on the order of a few nanometers. The next challenge for us is to integrate
oxide nanostructures into these devices and attempt to probe the properties of oxides in structurally and
electronically confined geometries.

As was originally planned, the themes of my research activities are around many-body physics of semiconductor
nanostructures. My activities are summarized as follows:
1) Collaboration on the Mott transition in one-dimensional system
The Mott transition in an optically excited semiconductor has been one of the most important issues of many-body
physics of semiconductors, especially for one-dimensional systems. It was a very opportune time and place to
conduct research on this topic. Akiyama san’s group has the cleanest quantum wire samples in the world with the
best spectroscopic data obtained recently. They have for the first time measured both photoluminescence and
absorption spectra simultaneously under the same conditions. Such clean spectroscopic data allow some of the very
central issues of the Mott transition be analyzed in detail. I have spent a lot of time trying to understand the full
implication of their recent data to the Mott transition. I had almost daily discussions with Akiyama san on this issue
and on the understanding of their data. Together we have concluded the following on the Mott transition:
a) The optical gain observed in their system is due to biexciton to exciton transition. This is the first observation
of biexciton gain in a 1D system. This conclusion is based on the following features of the spectral data:γ) the
gain bandwidth is very narrow, corresponding to a dephasing time of more than 5 picosecond which is longer
than the typical dephasing time in a plasma, excluding degenerate plasma as a source of gain; δ) optical
gain occurs at a much lower density and when the photoluminescence spectrum still shows clear exciton and
biexciton peaks; and ε) the gain occurs when the biexciton peak overtakes exciton peak in the PL as total
pair density increases. The observation and understanding of such biexcitonic gain are significant in several
ways: It shows for the first time that optical gain can occur in a 1D system before the Mott transition and it
will allow much lower threshold quantum wire lasers be made than is achieved hitherto.
b) The Mott transition occurs through several stages of coexistence between excitons, biexcitons, and free
electron-hole plasma. We have identified four stages from free exciton gas, through biexcitons, to free plasma.
These research results provide a more complete picture for the Mott transition and shed light on the nature of
the Mott transitions in 1D system. We have plans of conducting more experimental investigations to fully
establish a complete picture of the Mott transition.
The results of our collaboration are contained in a manuscript entitled “Biexciton gain and the Mott transition in
GaAs quantum wires”, authored by Hayamizu, Yoshita, Ning, Takahashi, Akiyama, Pfeiffer, and West and just
submitted to Phys. Rev. Lett.
2) Investigation of the possibility of two-photon laser based on semiconductors
Together with Akiyama san we analyzed different possibilities of a semiconductor two-photon laser. We analyzed
both intersubband transitions in semiconductor quantum wells and biexcitons in CuCl system. The very long
phase coherence time of biexciton waves in CuCl provides a very appealing alternative to our original idea of using
intersubband transitions. In addition, the large biexciton binding energy (of ~20 meV in CuCl) allows enhanced
degenerate two-photon process, while keeping the competing one-photon exciton process sufficiently detuned far offresonance. But we realized that the published results by Gonokami’s group on this system are not likely to lead to a
8
continuous-wave optical gain because of the pre-dominating absorption process. We also had discussions with Prof.
Gonokami of Applied Physics Department, University of Tokyo. Our discussion led to a possibility of arranging
samples and pumping beam configurations such that two-photon emission process is kept unchanged, while twophoton absorption process is inhibited or significantly weakened. Such scenario is likely to lead to a CW two-photon
gain in CuCl.
Currently we are still analyzing this scenario in more detail. Possible collaboration with Prof.
Gonokami on this issue will be pursued.
3) Bandgap renormalization in 1D system
One of the well-known phenomena in semiconductor optics is the bandgap renormalization due to Coulomb
interaction. So far theories and experiments have shown strikingly conflicting results: While experiments by
Akiyama san’s groups and others have shown almost no bandgap shrinkage up to a very high density, while all the
theories so far have predicted continuous bandgap shrinkage starting from a very low density. This issue is also
closely related to the Mott transition. After my extensive study of the existing literature in the field and extensive
discussions with Akiyama san, we realized that the reason for such conflicting pictures between theories and
experiments is because all the theories have used the total electron-hole pair density for the calculation of bandgap
renormalization. We believe that such a use of the total density is not justified, since at very low density, majority of
the total density is in the form of exciton gas or in the co-existence phase of excitons and biexcitons. They do not
contribute to bandgap renormalization in the way as assumed in the current theories. This idea is the key in a
possible resolution of this contradiction. Dr. Huai of Osaka University has conducted preliminary estimate based on
our assumption and the results have show a much more consistent bandgap renormalization with experimental
measurements. The work is still continuing on this issue in collaboration with Prof. Ogawa’s group.
4) Interactions with other groups in Japan
In addition to my activities at ISSP described above, I also used this opportunity to interact with other groups in
Japan. We had extensive interaction with Prof. Ogawa’s group at Osaka University. Prof. Akiyama and I visited
Osaka group and Dr. Ping Huai (Postdoc of the Osaka group on a joint Akiyama-Ogawa project) visited Akiyama san
and me twice during my stay. Currently we are still continuing our collaboration on semiconductor quantum wire
lasers. We have also visited Prof. Gonokami’s group of the Applied Physics Department, University of Tokyo and had
extensive discussions with him on the two-photon laser as mentioned above.
5) Talks and conferences
During my stay, I also participated in two international conferences on behalf of ISSP and gave following talks:
b) Plenary talk entitled “Semiconductor Nanowires for Nanophotonics: Progress in Theory and Experiment”,
Conference on Optical Properties of Condensed Matter, Xiamen, China, August 4th-August 10th , 2006
c) Invited talk entitled “Compound semiconductor nanowires as nanolasers” at International Symposium on
Compound Semiconductors, Vancouver, Canada, August 13-August 17, 2006
In addition, I gave following talks at Akiyama group seminar
d) Selected issues of many-body effects in semiconductors, August 26, 2006
e) Semiconductor nanowire nanophotonics, September, 2006
Acknowledgement: First of all, I would like to thank the ISSP Director and his staff for arranging a very fruitful
visit. I would like to thank in particular my host, Professor Akiyama for his readiness to discuss physics all the time
and anytime. He has made my visit a very successful collaboration. I would also like to thank Kameda san of the
ISSP-ILO for being very thoughtful and helpful with every thing from small to big. She is great! I also thank Bessho

My participation in ISSP fundamental physics investigations started a few years ago, when Kubota laboratory
decided to use the NMR method of Homogeneous Precession Domain (HPD) for studies of superfluid 3He in Aerogel
under rotation. Why are these investigations so important, so that a physicist like me from the other side of the
globe comes repeatedly to Kashiwa and leaves his own investigations for a time? The answer is simple: because ISSP
has a unique installation, the nuclear demagnetization refrigerator on a fast rotating platform. Now we have three
such platforms, in Helsinky, Manchester and Kashiwa. The rotation of superfluid 3He is very fundamental problem
of macroscopic quantum physics. The coherent quantum state can not rotate at all. The same effect appears in
superconductors, where role of rotation is played
by magnetic field. The vacuum of our universe is also in a
coherent quantum state. The rotation indeed can be performed with creation of topological defects (vortices, cosmic
strings as well as other types of defects)
In Helsinki, where I have been taking part in investigations during last 25 years, starting from montage of the
first rotating platform, we found and investigated, surely under rotation, about 15 different types of vortices in
superfluid 3He, including vortex sheets and spin-mass vortex. Many of these vortices have been predicted, but for the
cosmic strings in the Universe. And this is the main beauty of fundamental physics. One can study the properties of
one system in full analogy with another which looks completely different. Manchester group studied the rotation of
3He
in a slab geometry and found… the additional mechanism of vortex dissipation, which was explained by Volovik
as an analogy of hypothetical mechanism of particles creation in the Universe. Particularly it is interesting that this
mechanism can explain the fact that in our part of the Universe we can see only matter but not antimatter. It
remains hypothesis for the Universe, but it is now reality for superfluid 3He!
ISSP platform can rotate at least a few times faster than others. It is really an extreme condition for superfluid
3He.
We can study here the vortex types and the phase diagrams, which no one else has observed before. Furthter
more, we can even put, inside 3He, Aerogel, a network of impurities, and see the effects of rotation. These studies
have been performed in ISSP during last a few years.
My particular interest is the influence of mass rotation on another coherent quantum state, HPD. This is the
magnetic coherent state, which manifests itself as the condensation of spin waves in a single quantum state. We
have found it in 3He-B in 1984 in Kapitza institute, Moscow. The full collection of quantum phenomena, usual for
superfluidity and superconductivity, was demonstrated, including Josephson effect on Spin Supercurrent. HPD has
been used in Helsinki to investigate the transient processes at the acceleration of rotation, as well as the spin-mass
vortex and its dynamics. Now in Kashiwa we suppose to use HPD for studying the transient processes at
acceleration 3He in aerogel.
My three months visit to Kashiwa was organized to make these investigations. But, as usual in physics, the nice
surprise can suddenly appear. In addition to the planned study, we have found a new magnetic coherent quantum
state, now in A phase of 3He. This state was predicted by Volovik and me in 1993. Manchester group tried to observe
it in a slab geometry, but unsuccessful. In our ISSP experiment we have used pressurized aerogel, which oriented
the order parameter in a single direction, preferable for the observation of the new coherent state. This our discovery
is very fundamental for physics of magnetic coherent states, as well as a new and fast developing field of applied
physics.

My stay at the ISSP during the months of September to November of 2006 was hosted by Prof. M. Kohmoto. For
about ten years I have been doing research in areas closely related to the quantum Hall effect (QHE), and have
known of Prof. Kohmoto’s extensive research in problems related to electron transport in incommensurate and
quasiperiodic systems for about the same amount of time. In particular, Prof. Kohmoto’s research has been key in
understanding the effects of the crystalline structure in the QHE in connection to the elegant Hofstadter’s problem
and beautiful “Hofstadter’s butterfly.” In late 2005 I contacted Prof. Kohmoto and prepared an application for the
visiting professorship for the 2006-2007 period and the application was accepted in early 2006. Upon my arrival in
September 1st, we had a period of intense scientific discussions and many members of Kohmoto’s group (Dr.
Masatoshi Sato, Dr. Takahiro Aoyama, and Mr. Daijiro Tobe) gave short presentations of their research for my
enlightenment. After that we focused on the problem of electronic spin transport. Given our common backgrounds in
the QHE and the Hofstadter problem, we decided to consider the effects of spin-orbit coupling in the transport of
electrons in systems with competing periods. Our efforts have uncovered a possible spin-induced delocalization in
these systems and the results obtained so far were presented in an ISSP seminar last week (Spin-orbit induced
delocalization in quasiperiodic systems). We have also submitted an abstract to the American Physical Society’s
March 2007 meeting (Spinorbit coupling in quasiperiodic systems, C. Wexler, D. Tobe, and M. Kohmoto) and we are
working on a manuscript to be submitted to the Physical Review B. Overall, I gained significant experience in an
area I had not previously worked directly, and have made new scientific contacts with whom I expect to keep
collaborating in the future.
On a more personal level, I would like to thank the hospitality of all people here in the ISSP, but in particular of
Ms. Akiko Kameda and Ms. Mihoko Kubo of the ILO, who worked hard to make our stay very pleasant. The
accommodations (apartment) provided for myself and my family (my wife and 5 year old son) were excellent. Ms.
Kameda also helped locate an Englishspeaking kindergarten/pre-school (almost) nearby (in Kita-Kashiwa) which
proved very good for my son. We all had a wonderful experience in Japan; in fact, my son says he wants to come to
live here!
I do have one negative comment to make, whose solution seems very easy, so I will provide it as well. The problem
is that, while there is excellent science being done at the ISSP, it is not easy for a visitor to get a real sense of the
research here because of difficulty in establishing contacts between the foreign visitors and local researchers.
Conversely, I believe that the fraction of ISSP researchers who become aware of the visitors’ research is also
minimal due to the same lack of contact. I, for once, was not asked to give a single seminar based on my research
background which I find very surprising and counterproductive (why not use the opportunity given by the presence
of numerous visitors to get a broader vision of what is being done elsewhere?). Although some of the lack of
interaction may be attributed to language issues, this is not a sufficient reason and a solution should be sought. In
most institutions I visited, visitors are asked to give a seminar early-on after their arrival. This helps “break the
11
ice,” and facilitates further contacts. I believe that this should be instituted as an “unofficial policy” of the foreign
visitors program: visitors should give a seminar upon arrival and the seminar should have plenty of time for
informal discussions afterwards. Of course, “locals” should also give plenty of seminars for the benefit of the
“visitors,” but this is done to a certain degree already, and it may be logistically difficult to implement on a wider
scale given the large number of ISSP researchers.
As for my impressions of the science done at the ISSP: it seems quite excellent, indeed. The research done here is
on par with the best institutions in the world. Being a theorist, I cannot say much about the laboratories, but the
parts that affect me (computer support, networking, libraries, access to information and office space) are truly
excellent. Secretarial staff was very competent and the students and postdocs I was fortunate to interact with were
all very bright and selfmotivated.
Overall, I was very happily impressed with the ISSP and Japan in general. I had an excellent visit from the
science point of view, and my family and I truly enjoyed the unique experience that a visit to Japan is. I would like
to thank the ISSP for its hospitality, organization, and the generous financial support provided.

We report in this paper an anomalous magnetic ordering process inthe charge ordered LuFe2O4. The neutron
scattering experiments wereperformed on TAS-1 and TAS-2 instruments installed at JAEA-JRR-3. Thefollowing
results are obtained: 1) Despite the triangular configuration a strong 2-D antiferromagneticcorrelation with
ferrimagnetic component in the double layer in thehexagonal plane develops to a 3-D order along the c-axis at
TN=242K. 2)
At around 177K there is another characteristic temperature Tf, where newtype of broad magnetic peaks start to
grow and at the same time the magneticpeaks already developed below TN also acquire finite line width,
includingthe peaks due to the ferrimagnetic component. A strong hysteresis isobserved at Tf. 3) Field dependence of
Tf was investigated. Upon applying the fieldperpendicular to the layer plane, Tf decreases and vanishes above
3T.The existence of the anomalous magnetic ground state will be demonstratedand the possible relation to the
orbital degree of freedom will bediscussed. 53

The transition metal oxides display an impressive variety in their physical properties, originating from the interplay between crystal field and hund's rule couplings in combination with the interactions with and between the
charge, lattice, spin, and orbital degrees of freedom. Famous examples are the cuprate high temperature superconductors and mixed valence compounds like magnetite and many vanadates. Charge ordering phenomena, low dimensional quantum magnetism, and superconductivity are but a few of the intriguing phenomena observed in the
transition metal oxides. This presentation will highlight some specific examples, focusing on the charge ordering and
non-linear charge transport in beta-sodiumvanadate, and the unusual spin-Peierls route in the titaniumoxyhalides.

Many properties of solids (e. g. the electrical conductivity) are governed by elementary excitations and relaxation
due to electron-electron or electron-phonon scattering. The dynamics of these processes occur on a femtosecond (fs)
time scale and can be probed directly by time-resolved photoemission spectroscopy. In our experiments the time evolution of the electron distribution function following optical excitation (50 fs, 1.5 eV) is monitored by 6 eV fs laser
pulses. This provides access to both occupied and unoccupied states around the Fermi level [1].

This talk addresses recent studies of electron and coherent phonon dynamics in several materials exhibiting different aspects of electronic correlation. For the ferromagnetic Gd(0001) surface the ultrafast drop of the spin polarization observed by magneto-optics is attributed electron-magnon scattering [2].
In the Mott insulator TaS2 electronic excitation induces an ultrafast insulator to metal transition and subsequently pronounced oscillations of the spectral function due to a coherent phonon mode [3].
Finally, first results of electron cooling in a high Tc superconductor (BiSCO) will be discussed.

In heteroepitaxy, the strain energy caused by the lattice mismatch competes with kinetic processes to form nanostructured films [1,2].
Ge on Si is a model system with 4.2% lattice mismatch that follows the Stranski-Krastanov growth mode:after
wetting the surface up to a critical thickness of 3-5 monolayers, it is not favorable to grow layer by layer and a
roughening transition to 3D islands is observed. In this system Ge/Si intermixing has been shown to be significant, as
it alters the composition and overall properties of the as grown Quantum Dots (QDs) [3].
Here I describe Ge-Si intermixing from individual islands measured in situ using X-Ray Photoemission Electron
Microscopy [4,5].
Using Ge/Si as a test system, we have developed a technique which allows to map the chemical concentration of
individual Ge(Si) nanostructures with a lateral resolution of 25 nm [6].
Finally, I will describe Scanning Tunnelling Microscopy and Low Energy Electron Microscopy results related to the
positioning and stability of Ge/Si nanostructures [7,8].
