Monte Carlo study of the effect of an applied field on the molecular organization of polymer-dispersed liquid-crystal droplets.

We have studied the effect of an applied field on a system of particles interacting with a LebwohlLasher potential, enclosed in a polymer-dispersed liquid-crystal droplet with radial boundary conditions. We have used Monte Carlo simulations on a wide temperature range for systems of N = 304 and 5832 particles with positive susceptivity anisotropy, and we have calculated order parameters, the molecular organization, and powder-type deuterium NMR line shapes for eight different fieldstrength values. The effect of the field on the molecular organization is discussed.
