Research Interests


1. Experimental soft condensed matter physics

microscopic kinetics in various phase transitions using colloids model systems; crystal, amorphous solid and their crossover; surface phenomena of solids; the motions and clusters of novel granular systems.


2. Statistical physics

We apply the complex-network analysis to phase-space studies and discovered that the phase spaces of frustration spin models, lattice gases and spin glasses share some common features. We analytically prove that the spectra of their phase spaces are Gaussian, which represents a new class of network. A math by-product is a one-to-one mapping between 2D jigsaw-puzzle tiling and 3D stack of spheres. We are also interested in configurational temperatures and Brownian motions.
