Division of Condensed Matter Theory

In this Division, we are conducting vigorous theoretical research from a microscopic point of view on topics at the forefront of contemporary condensed matter physics, statistical physics, and materials science, also in collaboration of experimental groups. Our goals include theoretical elucidations of experimental results, developments of new concepts to describe collective behavior of interacting systems, useful theoretical modeling of materials, and predictions of novel interesting phenomena. The topics in recent research span diverse areas as quantum phase transitions and critical phenomena in quantum spin systems and strongly correlated electron systems, heavyfermion physics, superconductivity in various materials, frustrated systems, dynamic processes and catalytic properties at surfaces, and quantum transport and interactions in mesoscopic conductors. A wide variety of methodologies, including modern approaches based on mathematical concepts such as topology, many-body perturbation theory based on quantum field theory, and large-scale, state-ofthe- art computational approaches such as quantum Monte Carlo simulations and ab-initio calculation of electronic structures based on the density functional theory, are utilized to approach these problems. Each member of this Division employs calculation techniques in accordance with his/her expertise and taste. As a whole, this Division and related Theory Groups cover a wide range of problems and methodologies in the cutting-edge condensed matter theory.
