Summary

Here we examine the feasibility of a spatially homogeneous controlling of side-branching by oscillating pressure (that influences the melting point via to the Clausius-Clapeyron equation) and periodic Joule-heating. Computer modeling based on a two-dimensional (2D) phase-field theory [4] is used here to identify the resonance conditions, while the predictions are compared to experiments performed on quasi-2D liquid crystal layers, in which the nematic-smectic B transition mimics the crystallization of a liquid [5].
