  • Title: Chirality and biaxiality in cholesteric liquid crystals.
    Author: Dhakal S, Selinger JV.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2011 Feb; 83(2 Pt 1):020702. PubMed ID: 21405809.
    Abstract:
    We investigate the statistical mechanics of chirality and biaxiality in liquid crystals through a variety of theoretical approaches, including Monte Carlo simulations, lattice mean-field theory, and Landau theory. All of these calculations show that there is an important interaction between cholesteric twist and biaxial order: The twist acts as a field on the biaxial order, and conversely, the biaxial order increases the twist, that is, reduces the pitch. We model the behavior of chiral biaxial liquid crystals as a function of temperature and discuss how the predictions can be tested in experiments.
