Making full use of various―both analytical and
numerical―quantum statistical methods, we explore
novel quantum cooperative phenomena in strongly
correlated electron systems. A recent keyword is
"topology". Interpretation of phenomena must be
our ultimate goal, but we often take further
interest in the mathematical and methodological
ways we can accomplish this. We construct
microscopic theories on a variety of physics
such as quantum spin liquid, photoinduced
magnetism, nuclear magnetic resonance, inelastic
neutron scattering, Raman scattering, optical
conductivity, and angle-resolved photoemission
spectroscopy. We sometimes enjoy theoretical
formulation in itself and sometimes interpret
observations in cooperation with experimentalists
and chemist.

We develop new materials in strongly correlated electron
systems by various chemical methods including high
pressure synthesis, and elucidate their properties
by both bulk physical properties measurements (electrical
resistivity, magnetization, specific heat measurements,
and precise measurements in ultra-high magnetic fields,
etc) and microscopic measurements (μSR, neutron and
synchrotron X-ray scattering, etc).
Specifically, we develop frustrated magnetic materials,
multipole materials, skyrmion materials, novel actinide
compounds and also search for quantum many-body states
in high magnetic fields, cross- correlational phenomena,
and new superconducting states and odd-parity multipoles.

We study the interaction of light with matter, mainly
by spectroscopic measurements using laser light. Target
systems include organic materials, metals, and semiconductors.
In the case of molecular luminescence in solution, we deal with
energy relaxation of a few milliseconds due to liquid dynamics;
in the case of excited-state relaxation in semiconductors,
we measure relaxation in microseconds to nanoseconds; and in
the case of phonon spectroscopy in solids, we study relaxation
phenomena on time scales of picoseconds or less. We also synthesize
nanocrystals of a few nanometers in size by chemical synthesis
methods and study various phenomena caused by quantum effects
in the electron system confined in very small nanocrystals.
