Similarity and Dissimilarity between Influences of Anchoring Walls and of External Fields on Nematic and Smectic a Phases

چکیده
The McMillan liquid crystalline models under the influence of homeo-tropic anchoring walls and of external fields are investigated. For thin systems, the existence of the critical thickness, below which the system does not undergo a discrete phase transition, is confirmed. Apparent differences between the influence of the anchoring walls and of external fields are elucidated by investigating the order parameters and a temperature vs external field phase diagram for the bulk systems.

Director Structures in a Chiral Nematic Slab: Threshold Field and Pitch Variations
Abstract The liquid crystal director distribution is determined for a confined chiral nematic slab. The molecular director distribution of the field-controlled chiral nematic slab is directly calculated. The director profiles for the tilt and the twist angles, under different applied fields, are calculated in the slab with weak boundary conditions. Then, the dependence of the threshold field on...

In this paper, the director distribution is calculated for a nematic liquid crystal, in the cell with different surface anchoring conditions and external fields. The effects of finite and infinite surface anchoring on molecular orientations for one dimensional geometry are discussed. In these situations, the planar alignment is considered. Then, in a two dimensional geometry the planar and homo...
متن کاملExistence of Solutions to Boundary Value Problems for Smectic Liquid Crystals
We prove lower semicontinuity and lower bounds for a Chen-Lubensky energy describing nematic/smectic liquid crystals with physically realistic boundary conditions. The Chen-Lubensky energy captures stable phases of the liquid crystal material, ranging from purely nematic or smectic states to coexisting nematic/smectic states. By including appropriate additional terms, the model includes the eff...

After a short review of nematic liquid crystals and their interactions with the external fields, we investigate the effect of a disordered field which destabilizes the orientational molecular order of a nematic film. We analyze the effect of the disorder in the applied field on the pseudo-Casimir force which is induced due to thermal fluctuationsbetween the confining walls of the nematic film. ...
متن کاملSurface alignment, anchoring transitions, optical properties, and topological defects in the nematic phase of thermotropic bent-core liquid crystal A131.
We study optical, structural, and surface anchoring properties of thermotropic nematic bent-core material A131. The focus is on the features associated with orientational order as the material has been reported to exhibit not only the usual uniaxial nematic but also the biaxial nematic phase. We demonstrate that A131 experiences a surface anchoring transition from a perpendicular to tilted alig...
