Abstract

When an electric field above the Fréedericksz threshold is applied to a nematic liquid crystal in a cell with heterogeneous alignment layers, the system exhibits reverse tilt domains. Over a time scale of seconds to minutes, the disordered domain pattern coarsens into a uniform texture. Analysis of the coarsening dynamics shows that the characteristic length scale L grows with time t as L∼(log t)4. This scaling is consistent with predictions of the random-bond Ising model, in which randomness in the Ising bond strength represents heterogeneity in the alignment layers.
