ISSP Workshops
Future Research of Material Science Using Vacuum-Ultraviolet and Soft X-ray
Synchrotron LightMay 28-29, 2013
J. Fujimori, T. Kinoshita, K. Amamiya, T. Okuda, S. Shin, J. Yoshinobu, and F. Komori
Vacuum-ultraviolet and soft X-ray beamlines have been updated in the synchrotron light facilities in Japan including
SPring-8 and Photon Factory. In the end stations of these beamlines, advanced techniques for the studies of new materials are
now available by the improvement of polarization control and expansion of wavelength range with high energy resolution, andso on. Using these, we can expect more precise and quantitative measurements for studying new properties of the materials.
However, the synchrotron radiation facilities have lacked enough opportunities to share information on their individual development plan. This is not ideal for the present trend in the research of solid state physics that a target material is intensively investigated by several complimentary methods for the thoroughunderstanding of its properties and functionalities throughcooperative research. In this workshop, there were reports on
the current status and future plan of each synchrotron radiation facility in Japan and on the recent results at the advanced
beamlines including some of the oversea facilities as well as on
the plan of Tohoku medium-size synchrotron radiation facility.
Based on these reports, we discussed the future research using
vacuum-ultraviolet and soft X-ray synchrotron light. The
workshop provided an important opportunity for the community of this research area that the beamline scientists from all
the facilities and active users in Japan intensively discussed thefuture of their research field together.

Polar Oxides for Energy Conversion
June 26, 2013
M. Lippmaa, Y. Matsumoto, and I. Takeuchi
The focus of this workshop was on new oxide materials related to energy conversion applications. In particular, new typesof polar oxides may offer a way to design internal electric field gradients in oxide heterostructures for achieving efficient photocarrier separation. In addition to basic solar cell geometries, thedesire is to use functional oxides that fulfill two roles simultaneously, harvesting solar light by photocarrier generation andcatalytically enhancing photoelectrochemical reactions on thesurface. The presentations covered a broad range of related
topics: catalytic materials, synthesis techniques, surface analysis,
crystal design, phase transition mechanisms, and microstructural analysis. About 40 people attended the workshop, most ofwhom are young researchers. The event was thus a good venue
for in-depth discussions on new materials and new ideas on oxidematerials design. Two longer invited talks gave the attendees achance to think about more general materials lifecycle issues andto see a practical example how new materials, in this case thermoelastic alloys, transition from pure basic science research to anactual application.

Recently, large high-magnetic field laboratories have been built in many countries all over the world. Progress in thelast decade on both generation- and measurement-techniques makes it possible to carry out various experiments under highmagnetic fields. New development of materials science has started, as well, such as a fusion of high field with other fields (e.g.
synchrotron radiation light source or laser). A fusion of high magnetic field, new materials and probe is required to develop
an advanced research on materials science for the next decade. High
Magnetic Field Co-laboratory Project also contributes to the progress ofhigh field science. The project was planned to connect Japanese large highfield laboratories strongly and has been realized partially. An exchangeof researcher has been promoted in accordance with the project. This
workshop was held to discuss the issues noted below.
1) Search for a new research subject for the next decade and trainingof young researchers2) Development of research subject fused with other fields
3) Complete realization of High Magnetic Field Co-laboratory Project
The three issues were discussed not only by the high field laboratories but also by the users community. It was very significant for the highfield community that all researchers concerned with high field gathered
together to discuss the above issues and exchange recent information.

After the 2011 Tohoku earthquake, the scientific studies towards energy conversion and green environment have been extensively carried out. This workshop has focused on fundamental researches of novel materials and physical sciences related toenergy and environment.
The energy conversion system and recent novel materials have hierarchical structures. For example, solar cell is a complexsystem, composed of synthetic molecules, charge transfer pairs, p-n interface, semiconducting layers, and buttery device. As
attractive soft material, ionic liquid is also a hierarchical system with nano-meso-micro correlation lengths. The scientifickeywords of these systems are “multi-energy scale”, “dynamic structure”, and “excited state”. Therefore, it is important to perform researches
integratedly.
In this workshop, the active 39 researchers have afforded 30-min.
keynotes and 20-min. oral presentations in the sessions of “solar
cell · artificial photosynthesis”, “photo-catalyst”, “battery”, “surfacescience”, “molecular materials · organic electronics”, “bio-materials”,
and “hydrogen-based-materials”. The 24 graduate students and young
researchers have presented their researches in the poster session. Totally,
198 participants for 3 days participated in the workshop with hot discussions. It is meaningful that prominent researchers in a wide range ofscientific fields presented their cutting-edge research results and exchange
their information.

K. G. Nakamura, T. Suemoto, N. Sarukura, S. Koshihara, H. Noziri, and M. Yoshimura
Ultrahigh pressures (>1TPa) and magnetic fields (>1kT) are recently realized by using a high-power laser, and electronicand structure dynamics in condensed matter can be studied under these extreme conditions. In this symposium, we discussed
generation techniques of such extreme fields, current research activities, and future topics. The symposium consisted ofsessions on (1) physics under strong magnetic fields, (2) physics under ultrahigh pressures, and (3) ultrafast measurements,
with seventeen presentations. On the topics (1) there were presentations of a recent generation technique of the kT magnetic
field using high-power laser plasma and measurements with synchrotron radiation, laser, and neutron diffraction under pulsed
magnetic fields. On the topics (2), the generation of laser-induced ultrahigh pressures over TPa, which cannot be accessed bystatic compression, and combination research works
with X rays from XFEL (X-ray Free Electron Laser)
were presented. In addition, studies on planetaryscience using shock-induced high pressures were alsopresented. On the topics (3), single-shot measurement
techniques are presented to study ultrafast phenomenausing laser combined with pulsed electrons and X rays.
Throughout the symposium, we discussed the problemsof pulsed high pressure and magnetic fields and potential for studying unique properties of materials under
non-equilibrium conditions.

Local Symmetry Breaking and Quantum Properties in Strongly Correlated Electron Systems
November 27-29, 2013
T. Arima, H. Harima, S. Nakatsuji, and Z. Hiroi
Symmetry is one of the most important concepts to determine the physical properties of solid states. For example, many
interesting phenomena such as unconventional superconductivity, multiferroicity, and spin Hall effect are relevant to thebreaking of the global space-inversion symmetry and resultant antisymmetric spin-orbit interaction. The antisymmetric spinorbit interaction can be activated at non-centrosymmetric atomic sites even in materials with global space inversion symmetry.
At such non-centrosymmetric sites, an odd-parity ligand field also allows the emergence of odd-parity multipoles like magnetic
quadrupole and electric octupole moments, which may open the door to new paradigms in material science.
This workshop was organized to shed light on the possible exotic properties induced by the breaking of local inversion symmetry coupled with the electron correlation and spin-orbit coupling. During the workshop, off-diagonal responses,
quantum transport, and exotic superconductivity
were intensively discussed in terms of multipoles.
In particular, many itinerant systems hosting thedegree-of-freedom of various multipole moments
were intensively discussed. The number ofparticipants reached 87, consisting of researchers
in the fields of 4f-electron systems (rare-earthcompounds), 5f systems (uranium compounds), andd-electron systems (transition-metal compounds).
The discussions across the various communities
in solid state science made the workshop very
successful.

Joint Researches in Foreign Neutron Facilities

January 29-30, 2014
T. Masuda, M. Shibayama, H. Yoshizawa, and O. Yamamuro

Since the Great East Japan Earthquake on 11th March in 2011, Japan Research Reactor (JRR3) has suspended its operation and the Neutron Scattering Laboratory (NSL) has had difficulty in the domestic joint research using neutron spectrometers
installed in JRR3. Now the NSL provides the neutron users the travel budgets for the neutron experiments at foreign facilities
and supports the joint researches. In this workshop the users presented and discussed the researches performed at the foreign
facilities. The field covers wide range including magnetism, strongly correlated electrons, glass, and soft matter. As for magnetism, the topics on geometrically frustrated systems were focused; the complex magnetic structure in chiral magnet, novel
magnetic phase in quantum spin ice, the interplay between magnetic structure and electric polarization in multiferroics, etc.
As for strongly correlated electrons system, studies on magnetic excitations and structures in various types of superconductors
including high-Tc Cu oxides, Fe pnictides, and heavy-fermion
materials were presented. It should be noted that the development and application of high pressure cell were implemented
even in the restricted machine time at foreign facilities. Structural and dynamical analyses on new materials in the field ofsoft matter and quasi-elastic scatterings on cluster structure
and ion liquid in the field of glass were reported. With 25 talks
and 17 posters, the discussions at the workshop were hot andfruitful, indicating the scientists in the field of neutron scattering
are actively doing their research and even enjoying this hardsituation.

February 19, 2014
S. Shin, F. Komori, I. Matsuda, and Y. Harada

Five years has passed since the University of Tokyo started constructing an undulator beamline BL07LSU in SPring-8, and
it is the middle of the project period using exclusively the beamline for joint studies. Polarization-controlled high-brilliancelight is now available in the beamline, and used for advanced spectroscopy at the end-stations for material science. The numberof publications from the beamline users has increased recently, and attracted much attention over the world. As a result, theoverseas researchers continuously apply their joint studies there, and more than 30 % of the beam time for the joint studies isused with the foreign collaborators at present. In this workshop, the present status of the undulator light and the recent results atthe end-stations were reported, and the advancement of the beamline in the next five years was discussed. In particular, future
use of the polarization switching was proposed in relation to the development of the variable-polarization undulator. For thenext two years, three long-term projects have been accepted at the three stationary end-stations for time-resolved spectroscopy,
three-dimensional nano ESCA and soft X-ray emission spectroscopy. Each research plan with common keywords of operando
and polarization control was introduced and discussed.
New research plans using the free port were presented aswell.
