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.
