Dynamics of fluid-liquid crystalline interfaces and heterogeneous growth using the Phase Field Crystal Model for Liquid Crystals — •Cristian Vasile Achim and Hartmut Loewen — Institut für Theoretische Physik II - Soft Matter, Heinrich-Heine-Universität Düsseldorf

Phase Field Crystal Model for Liquid Crystals is formulated with respect with three position-dependent order parameters, the reduced translational density, the local nematic order parameter, and the mean local direction of the orientations. The free-energy involves local powers of the order parameters up to the fourth order, gradients of the order parameters up to the fourth order, and different couplings among the order parameters. The phase diagram was investigated in Phys. Rev. E 83, 06172 (2011). Among stable phases liquid crystalline states are isotropic, nematic, columnar, smectic-A, and plastic crystalline phases. In this report we present results regarding the dynamics of fluid-liquid crystalline interface and heterogeneous growth obtained by solving numerically the couple equation of motions of the order parameters as presented in J. Phys.: Condens. Matter 22 (2010) 364105.
