Modeling nematohydrodynamics in liquid crystal devices

COMPUT PHYS COMMUN 147:1-2 (2002) 7-12

Authors:

G Toth, C Denniston, JM Yeomans

Abstract:

We formulate a lattice Boltzmann algorithm which solves the hydrodynamic equations of motion for nematic liquid crystals. The applicability of the approach is demonstrated by presenting results for two liquid crystal devices where flow has an important role to play in the switching. (C) 2002 Elsevier Science B.V.

Quantum Hall ferromagnets, cooperative transport anisotropy, and the random field Ising model

ArXiv cond-mat/0208024 (2002)

Authors:

JT Chalker, DG Polyakov, F Evers, AD Mirlin, P Woelfle

Abstract:

We discuss the behaviour of a quantum Hall system when two Landau levels with opposite spin and combined filling factor near unity are brought into energetic coincidence using an in-plane component of magnetic field. We focus on the interpretation of recent experiments under these conditions [Zeitler et al, Phys. Rev. Lett. 86, 866 (2001); Pan et al, Phys. Rev. B 64, 121305 (2001)], in which a large resistance anisotropy develops at low temperatures. Modelling the systems involved as Ising quantum Hall ferromagnets, we suggest that this transport anisotropy reflects domain formation induced by a random field arising from isotropic sample surface roughness.
