ABSTRACT

We present large-scale lattice Monte Carlo simulations of nematic ordering in the vicinity of submicron objects — colloids or viruses — of different shapes (spherical, cubical or icosahedral) immersed in a nematic liquid crystal. We simulate polarized light transmission patterns for the various particles and find that they are distinguishable, suggesting that they might be useful for object shape recognition or, in case of viruses, for diagnostic purposes.
