1. Experimental soft condensed matter physics We investigate the microscopic structures, interactions, dynamics, pattern formation and phase behaviors of colloids such as micro-ellipsoids and diameter-tunable microgel spheres. Colloids are good model systems of atoms because trajectories of individual particles are measurable by video microscopy and image processing. Currently we are focusing on the melting, freezing and geometrical frustrations of colloids in two dimensions, three dimensions and thin films. 2. Statistical physics We apply the complex-network analysis to phase-space studies and discovered that the phase spaces of some frustration spin models and lattice gas models belong to a new class of network with unique topology. We are also interested in configurational temperatures and Brownian motions.
