Themeof research
Quantum information-theoretical knowledges such as entanglement
are powerful tools in many branches of theoretical physics. We aim toconstruct mathematical basis for next-generation interdisciplinary
physics by dealing with various problems such as condensed matterphysics, mathematical physics, and space-time physics. Issues ofparticular interest are: nonequilibrium dynamics of quantum manybody systems (dynamic phase control and relaxation processes of qubitmany-body systems), basic physics of quantum technologies such as
quantum measurement and quantum calculation, topological physics,
techniques of many-body physics (composite operators, tensor
networks, and singular value decomposition), and research on
information and space-time based on quantum/classicalcorrespondence.
We have been exploring novel energy-harnessing materials, such as
thermoelectric materials, photovoltaic materials, cathode materials forrechargeable batteries and high transition-temperature
superconductors. Functions of a solid substance primarily depend on
the electronic structure, directly derived from its crystal structure.
Through high-quality structure analyses using neutron and X-raydiffraction, combined with first-principles calculations, we havebeen fabricating materials with desired functions.
We are conducting the research and development ofsuperconducting quantum devices such as superconducting qubits
which are core devices of superconducting quantum computers,
superconductor/ferromagnet hybrid devices (π-junctions),
superconducting single-photon detectors, and quantum amplifiers. In
addition, with the aim of discovering room temperature
superconductivity and elucidating the mechanism, we are conducting
exploratory research and basic physical properties ofsuperconductors using soft chemical methods.
We are exploring the physics and engineering of autonomous andsoft systems like biological phenomenon. Especially, with a focus on
the mechanical motions such as the bacterial motion and biologicalnano-motors and the information processing such as the gene
replication, we are studying the physics of nano-sized autonomous
system subjected to thermal fluctuations. Furthermore, we aredeveloping a novel engineering concept to produce artificial
nanomachines by imitating the biological nano machineries.
This lab is newly found in 2023. We aim to accelerate quantum
communication technology by creating photofunctional materials
with glass and amorphous. They possess random structure without
grain boundary suitable for light manipulation. But even for glass,structural fluctuation limits the optical loss. By suppression of thefluctuation, glass with ultimate transparency is made. Controlling
fluctuations in the structure, or conversely, activating inhomogeneity
in structures enable us to create new functional materials.

Themeof research
Our laboratory is one of five steady high magnetic field facilities
in the world. We develop high filed magnets and superconducting
materials. In addition, the research in high magnetic fields on asolid state physics and superconducting materials, and a material
development under magnetic fields are performed using a 30 T
hybrid magnet, a 25T cryogen-free superconducting magnet and a20T superconducting magnet and so on.
Magnetic material is one of the key materials for future automobile
and aircraft electrifications and carbon neutrality issue such as motor
cores and power-electronics passive devices. Our target is to explore
the nanoscale magnetism and physics of various practical magnetic
materials and to realize the high-performance magnetic devices which
contribute to our future society.
Remarkable advances in nanotechnologies for semiconductor
lithography and for bio-science are expected by utilizing soft X-ray
with wavelengths less than 15 nm.
In order to manipulate the soft X-rays, we are studying anddeveloping cutting-edge optical-elements of high-performance and/ormultifunction, and our goal of the study is establishment of the soft
X-ray optical technology.
In the present project, a soft X-ray microscope has been
experimentally produced for high spatial resolution with the help of
optical interference effect, and is applied to the evaluation of the
microscopic electronic-structures of materials and high-resolution
observation of biological samples.
In addition, a new soft X-ray optical system has also been developing
to improve spatial resolution of soft X-ray microscopes.
Properties of matter, such as reactivity and functionality, aredetermined by the motion of electrons bound in matter. For this reason
we develop and employ new spectroscopic methods using high-energy
electron scattering in order, for instance, to visualize the electron
motion in stable species and more importantly the change of electron
motion in transient species, which is the driving force behind any
chemical reactions. The project involves:
1. Development of a real-time spectroscopic complex for visualizing
electron and nuclear motions during chemical reaction,
2. Molecular orbital imaging by electron momentum spectroscopy,
3. Development of multidimensional coincidence techniques forstudies of stereo-dynamics in electron-molecule collisions.

Theme of research
The main research themes are basic research and application ofoptoelectronic semiconductor materials such as (BAlGaIn)N andoxide semiconductors: epitaxial growth of their films andquantum structures; luminescence dynamics of excitons in them;coherent light source based on cavity polaritons.
Electrons and photons have a quantum mechanical property called"spin”. Our research focuses electronic and photonic devices fully
utilizing “spin”, the physics behind, and advanced materials forthese devices. For example, we are conducting research on
magnetoresistive devices utilizing both magnetic materials andsemiconductors to enhance the performance of nonvolatile
spintronic memory. We are also conducting research on Quantum
sensing using the semiconductor diamond to enhance theperformance and functionality of quantum-spintronic sensors.
