The Gay-Berne (GB) potential has proved highly successful in the simulation of liquid crystal phases, although it is fairly demanding in terms of resources for simulations of large (e.g., N>10(5)) systems, as increasingly required in applications. Here, we introduce a soft-core GB model, which exhibits both liquid crystal phase behavior and rapid equilibration. We show that the Hamiltonian repl...

We demonstrate a high-speed inline holographic Stokesmeter that consists of two liquid crystal retarders and a spectrally selective holographic grating. Explicit choices of angles of orientation for the components in the inline architecture are identified to yield higher measurement accuracy than the classical architecture. We show polarimetric images of an artificial scene produced by such a S...

As described in the previous chapter, the nematic (N) liquid crystal is characterised by a long range orientational order of the long axes of the molecules without a long range positional order of their centres of mass (see section 1.2.1, chapter-1). The preferred axis of orientation in the nematic liquid crystal, called the director, is represented by the unit vector n ^ . The extent of orient...

The change in the orientation of nematic liquid crystals due to the increase of the sample thickness is experimentally analysed. The data show that the phenomenon is a critical

The effect of director pretilt on the twist magnetic Fréedericksz transition of nematics was investigated in a planar cell. The director configuration was calculated as a function of magnetic inductance. The dielectric and optical response of the nematic liquid crystal was numerically modeled. A dielectric measurement method for determining the elastic constant K_{22} is presented. The influenc...

This article reviews recent advances in the Raman scattering study of oneand two-dimensional materials. The characteristic vibrational properties of the low dimensional crystals are described and various methods of characterizing these crystals are summarized. Recent experimental results on polymer crystals, inorganic chain-like crystals, layered crystals and intercalated layer crystals are pre...

Herein, we reported on a middle-aged woman presented with painless cervical lymphadenopathy. Past medical history was not significant. Pathologic examination of incisional biopsy show partial effacement of lymph node architecture with many reactive inflammatory cells admixed with Reed-Sternberg cells, many Charcot-Leyden crystals, and noncaseating granuloma. Immunohistochemical staining was pos...
