Akihiro ISHIBASHI

Position
Professor
Laboratory
General Relativity and Cosmology Laboratory
General Relativity, Gravitation, Cosmology

Investigation is conducted into overall space dynamics and black holes using general relativity. A focus of research is on high-dimensional space models and high-dimensional black holes, which look at the possibilities of high-dimensional space-time.

Kaiki Taro INOUE

Position
Professor
Laboratory
Laboratory for Cosmology
Cosmology, Astrophysics, Gravity

Dark matter and dark energy are mysterious substances that account for a large part of the universe. Solutions to these mysterious substances are sought using general relativistic phenomena on cosmic scales such as gravitational lenses, gravitational waves and cosmic inhomogeneity (halos and voids).

Nobuyoshi OHTA

Position
Professor
Laboratory
Elemental Particle and Gravity Theory Laboratory
Elemental Particle Theory, Quantum Gravity Theory, Superstring Theory, Cosmology

Studies are carried out on elemental particles, which are smaller than atoms, through the theory of relativity and quantum mechanics, and research is conducted into cosmology and the unified theory of elemental particles, including gravity, through the general theory of relativity and superstring theory.

Experimental Particle Physics

We know that matter is composed of things like quarks and other subatomic particles. But what are subatomic particles composed of? Using a large particle accelerator, research here tries to answer questions like this.

Yasushi KONDO

Position
Professor
Laboratory
Quantum Control Laboratory
Quantum Information, Condensed Matter Physics

Research is carried out with an interest in a wide range of control methods, in which quantum mechanics such as quantum information and quantum control play an important role. In particular, if quantum computers are realized, it will change the world. It is hoped that the elemental research conducted here will help make such computers a reality.

Michiyuki CHIKAWA

Position
Professor
Laboratory
Astroparticle Physics Laboratory
High-Energy Astroparticle Physics (1) Extreme High Energy Astroparticle Physics (2) High Energy Gamma-ray Physics

Research is conducted into the stars, galaxies, and space through observation of the high-energy astro-particles that fly about in outer space. The laboratory participates in joint international projects like the Cherenkov Telescope Array(CTA) Project and the Telescope Array(TA) Experiment to develop detection equipment.

Tomonari DOTERA

Position
Professor
Laboratory
Soft Matter Physics Laboratory
Quasicrystal Physics, Soft Matter Physics, Condensed Matter Physics

This laboratory is the world leader in soft quasicrystal research. This laboratory made the world’s first discovery of a polymeric quasicrystal, implying that even soft matter has an ordered structure with no repetitive units. Theoretical research on the origin of the formation of soft quasicrystals appeared in Nature. Recently Dr. Dotera found the bronze-mean quasicrystal. Also, he aims to develop the physics of gyroid.

Kenichi KASAMATSU

Position
Associate Professor
Laboratory
Laboratory of Theoretical Condensed Matter Physics
Theory of Condensed Matter Physics

A gas of neutral atoms cooled down to near absolute zero temperature causes a phase transition called Bose-Einstein condensation, resulting in quantum condensates possessing strange properties, as exemplified by superfluidity. We investigate various phenomena exhibited by atomic Bose-Einstein condensates.

Ippei Danshita

Position
Associate Professor
Laboratory
Quantum Many-Body Physics Laboratory
Theory of condensed matter physics, Theory of atomic, molecular, and optical physics, Theory of quantum control

In condensed matter systems, such as electrons in solids and liquid helium, competitions and/or collaborations of quantum nature and interparticle interactions lead to various interesting phenomena, including superfluidity, superconductivity, quantum phase transitions, and many-body localization. We develop theoretical methods describing quantum many-body systems, aiming to discover novel quantum many-body effects.

Masayoshi Nishiyama

Position
Associate Professor
Laboratory
Laboratory for Dynamic Living Systems
Biophysics, Bioimaging

Biomolecules are nanometer-sized molecular machines working in living cells. Our research goal is to elucidate the operating principle how biological molecular machines work efficiently in collaboration with water molecules.

Takahiko MASUI

Position
Associate Professor
Laboratory
Solid State Physics Laboratory
Condensed Matter Physics (experiments)

In the field of condensed matter physics, it’s possible to conduct research by creating one’s own specimens and measuring these. It is interesting in a completely different way than mega science. The goal here is to discover new physical phenomena and new matter, as well as solve long-debated mysteries of science.

Yohko YANO

Position
Associate Professor
Laboratory
Biophysics Laboratory
Biophysics, Chemical Physics, Structural Chemistry

Protein comes in various complex structures in the body in order to perform its functions. On the other hand, it easily changes form and loses its functions. These structural changes are observed using the world’s brightest X-rays in order to understand the mechanisms behind the formation of protein structures.
