Topological Defects in Spherical Nematics
Homin Shin, Mark J. Bowick, Xiangjun Xing
We study the organization of topological defects in a system of nematogens confined to the two-dimensional sphere (S^2). We first perform Monte Carlo simulations of a fluid system…
Nonlinear Elasticity, Fluctuations and Heterogeneity of Nematic Elastomers
Xiangjun Xing, Leo Radzihovsky
Liquid crystal elastomers realize a fascinating new form of soft matter that is a composite of a conventional crosslinked polymer gel (rubber) and a liquid crystal. These {\em soli…
Topology of Smectic Order on Compact Substrates
Xiangjun Xing
Smectic orders on curved substrates can be described by differential forms of rank one (1-forms), whose geometric meaning is the differential of the local phase field of density mo…
A Semigroup Theory of Rate Independent Hysteresis
Xiangjun Xing
We explore a macroscopic, algebraic approach to rate independent hysteresis using semigroup theory. A macroscopic description of metastable states relevant to rate independent hyst…
