报告人简介
Hidetoshi Fukuyama is a professor in Tokyo University of Science, and a professor emeritus of Tokyo University. He received Ph.D. in 1970 from Tokyo University. His research interests span a wide range of topics in theoretical condensed matter physics, focusing on quantum transport phenomena in solids in general, including high-temperature superconductivity, Anderson localization, spin-Peierls effect, orbital magnetism, Dirac electron systems, and molecular solids etc. He is a fellow of American Physical Society, and was the director of Institute for Solid State Physics of Tokyo University (1999-2003), the vice president of IUPAP (also the Chair of Commission 5: low temperature physics), the vice president of Tokyo University of Science (2010-2013), and currently is a research advisor to the president of Tokyo University of Science.

报告摘要:
Motions of electrons in solids are governed by the energy bands, which sometimes have features similar to Dirac electrons in vacuum in a region of momentum of physical interest. Well-known examples are bismuth and graphite; 4x4 original Dirac matrix in three-dimension with strong spin-orbit interaction in the former and massless Dirac (Weyl electrons) in two-dimensional layer stacks in the latter. Recent examples include one-layer graphene, layered bulk molecular solid, (BEDT-TTF)2I3, Iron-pnictide superconductors, inverse perovskite Ca3PbO and surface states of topological insulators. In this talk theoretical studies on characteristic physical responses in these systems such as anomalous diamagnetic and dielectric responses, spin Hall and Hall effect will be addressed by focusing on bismuth and molecular solids.
