研究方向
?
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, solid-solid transitions, glass transitions 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 frustration spin models, lattice gases and spin glasses share some common features. They established a new class of network with unique topology.?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.
