leader Susumu Saito   Nanostructured materials show a rich variety of electronic properties depending on the details of their atomic geometries. Nanocarbon materials, i.e., fullerenes, nanotubes, and graphene are good examples. We reveal and predict electronic properties of various nanostructured materials, and eventually design new nanostructured materials.
kawaisensei Nobuyuki Kawai   We observe gamma-ray bursts, gravitational wave events, black holes and neutron stars using astronomical satellites and ground-based telescopes to study the first stars in the Universe, birth of black holes, etc. We also develop instruments for these observations.
nishimori Hidetoshi Nishimori   The main topic is the basic theory of quantum annealing. In particular, we try to generalize the simple traditional protocol of uniform control of the transverse field to more advanced control including non-stoquastic Hamiltonians, inhomogeneous field and reverse annealing.
