Research Abstract

A system consisting of many elements goes to thermal equilibrium by temporal evolution. Thermal equilibrium is an object of theories for heat engines, and hence it is important for applications. However, a system with long-range interactions is frequently trapped at so-called a quasi-stationary state before reaching thermal equilibrium, and hence it is important to understand and describe the quasi-stationary states. This research project gives contribution to a nonequilibrium statistical mechanics for predicting the quasi-stationary states theoretically, and to a kinetic theory for describing dynamics of such a system.
