	Every material around us is composed of numerous atomic nuclei and electrons. It sometimes exhibits various fascinating interaction-caused phenomena that cannot be expected from single-particle viewpoint. Theoretical research of condensed matter physics aims to understand these phenomena and predict new properties based on thermodynamics, statistical mechanics, quantum mechanics, quantum field theory, etc. Our research target includes: 　Critical phenomena 　Many-body systems 　Low-dimensional quantum systems 　Interdiscipline from a viewpoint of statistical mechanics (optimization problems, 　　　neural networks, etc.) 　Development of numerical analysis methods 　Multi-pole ordered states 　Magnetic polaron in magnetic semiconductors 　Quantum interference due to tunneling effect in quantum dots 　Photo-induced phase transitions 　Nano magnetism 　Spintronics 　Trapped cold atoms 　Quantum wires 　etc. The Condensed Matter Theory Group actively works on a variety of topics, some of which are shown above, and leads graduate students to the frontier of the research of physics.
