In this decade, topological quantum phenomena becomes a hot topic stimulated by the discovery of quantum spin Hall effect. It is now a good time to explore physics of topological quantum phenomena. Our current research interest is topological superconductivity, topological insulator, topological crystalline insulator, Weyl semimetal, and exotic order in condensed matter.
・Superconducting Junctions（Tunnel effet, Josephson effect, Proximity effect）
・Symmetry of superconductivity
・Mechanism of Superconductivity
・Majorana Braiding Dynamics
・Atomic monolayers (Graphene, Silicene, Stanene)
・Dirac Semimetal, Weyl Semimetal
