Research Abstract

We investigated slow glassy behaviors of nematic liquid crystals confined in porous media by means of Monte Carlo simulation. In particular, we focused on the topology of the porous matrix. We found two relaxation modes in the glassy behaviors. The slow mode is attributed to the reconfiguration of the topological defects. We also found that the slow mode can be suppressed in regular shaped porous media, in which only the fast viscoelastic mode is observed.
