We theoretically study the fundamental problems in condensed matter physics and statistical physics as follows:

• In the high density quantal systems such as the high-Tc superconductors, the strong electron-electron correlations are considered to play crucial roles for manifestation of the superconductivity. From such a view of point, we are developing a new theory for the superconductivity beyond the BCS theory.
• We study intensively the quantal fluctuations inherent to the superconducting states, the charge density wave states, or the spin density wave states of the low dimensional organic conductors.
• We investigate dynamical phenomena related to crystal growth and, in particular, nonequilibrium pattern formation on solid surfaces.
