Shear dynamics in cholesterics

COMPUT PHYS COMMUN 169:1-3 (2005) 122-125

Authors:

E Orlandini, D Marenduzzo, JM Yeomans

Abstract:

We study shear dynamic in cholesteric liquid crystal using a lattice Boltzmann scheme that solves the full, three-dimensional Beris-Edwards equations of hydrodynamics. We show that the coupling between shear and the natural elastic deformation of cholesterics can induce twist in an initially isotropic phase. (c) 2005 Elsevier B.V. All rights reserved.

Orientational ordering and dynamics of rodlike polyelectrolytes.

Phys Rev E Stat Nonlin Soft Matter Phys 72:1 Pt 1 (2005) 011805

Authors:

Hossein Fazli, Ramin Golestanian, Mohammad R Kolahchi

Abstract:

The interplay between electrostatic interactions and orientational correlations is studied for a model system of charged rods positioned on a chain, using Monte Carlo simulation techniques. It is shown that the coupling brings about the notion of electrostatic frustration, which in turn results in: (i) a rich variety of orientational orderings such as chiral phases, and (ii) an inherently slow dynamics characterized by stretched-exponential behavior in the relaxation functions of the system.
