    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2011 Oct; 84(4 Pt 1):041705. PubMed ID: 22181155.
    Abstract:
    We present an investigation of the ordering in a nematic liquid-crystal film confined between two cylindrical surfaces with antagonistic (radial and planar) anchoring alignments. A Monte Carlo study of a Lebwohl-Lasher model with suitable boundary conditions has been performed to calculate the ordering and the molecular organization for different film thicknesses. The simulation results are compared with some theoretical predictions obtained with the elastic continuum approach. The agreement between theory and simulation is improved as the thickness decreases.
