Computer Simulations of Nematic Droplets with Toroidal Boundary Conditions?

We present Monte Carlo simulations of nematic droplets with toroidal boundary conditions (TBC) and various anchoring strengths and we investigate the orientational order and the molecular organizations in these systems that mimic polymer dispersed liquid crystals (PDLC). PACS: 02.50 Monte Carlo studies PACS: 61.30.Jf Defects in liquid crystals PACS: 61.30.Gd Orientational order of liquid crysta...

The diverse world of liquid crystals

Liquid crystals are all around us: in high-strength plastics, snail slime, laundry detergent, textile fibers such as silk and Kevlar, crude oil, insect wings, mineral slurries, lipstick, Bose-Einstein condensates, and the mantles of neutron stars. We eat them as aligned molecules in gluten and drink them as phospholipids in milk, where they stabilize fat globules. In our bodies they transport f...

Bond orientational order model for smectic B liquid crystals

2014 We show how recent theories of two dimensional melting can be carried over to provide natural order parameters for solid, smectic B, and smectic A phases of liquid crystals. Smectic B and other well-ordered smectic phases correspond to systems with bond orientational long range order and positional short range order in the plane of the smectic layers. The X-ray scattering predicted by this...

Universal power law in the orientational relaxation in thermotropic liquid crystals.

We observe a surprisingly general power law decay at short to intermediate times in orientational relaxation in a variety of model systems (both calamitic and discotic, and also lattice) for thermotropic liquid crystals. As all these systems transit across the isotropic-nematic phase boundary, two power law relaxation regimes, separated by a plateau, emerge, giving rise to a steplike feature (w...

Studies of Orientational Order of Some Nematogens by means of Raman Scattering Spectroscopy

The orientational behaviour of some liquid crystals with various molecular structures was studied by means of the Raman scattering depolarization method. The Raman scattering spectra of linearly polarized light were recorded as a function of temperature in the nematic phase. On the basis of these spectra the order parameters 〈P2〉 and 〈P4〉 as well as the molecular distribution function were dete...
