Description

Title:Sharp-interface nematic–isotropic phase transitions without flow
Author(s):Cermelli, Paolo; Fried, Eliot; Gurtin, Morton E.
Abstract:We derive a supplemental evolution equation for an interface between the nematic and isotropic phases of a liquid crystal when flow is neglected. Our approach is based on the notion of configurational force. As an application, we study the behavior a spherical isotropic drop surrounded by a radially-oriented nematic phase: our supplemental evolution equation then reduces to a simple ordinary differential equation admitting a closed form solution. In addition to describing many features of isotropic-to-nematic phase transitions, this simplified model yields insight concerning the occurrence and stability of isotropic cores for hedgehog defects in liquid crystals.
