Liquid crystal cells with "dirty" substrates
Leo Radzihovsky, Quan Zhang
We explore liquid crystal order in a cell with a "dirty" substrate imposing a random surface pinning. Modeling such systems by a random-field xy-model with surface heterogeneity, w…

Conical soliton escape into a third dimension of a surface vortex
Leo Radzihovsky, Quan Zhang
We present an exact three-dimensional solitonic solution to a sine-Gordon-type Euler-Lagrange equation, that describes a configuration of a three-dimensional vector field n constra…

Microscopic Wrinkles on Supported Surfactant Monolayers
Quan Zhang, Thomas A. Witten
We discuss mechanical buckling instabilities of a rigid film under compression interacting repulsively with a substrate through a thin fluid layer. The buckling occurs at a charact…
