Computer simulations of nematic droplets with bipolar boundary conditions.

Abstract

We present Monte Carlo computer simulations of model nematic droplets that mimic polymer dispersed liquid crystals (PDLC’s) with bipolar boundary conditions. We investigate the orientational order and the molecular organization in these systems for various anchoring strengths and for external applied fields of different magnitude both for positive and negative susceptivity anisotropy. We report a number of simulations for system sizes from 304 to 11752 particles and calculate powder deuterium NMR spectra and polarizing microscope textures for the various cases.
