"Electronic Liquid Crystals: Novel Phases of Electrons in Two Dimensions"

Alan Dorsey , University of Florida
[Host: Michael Fowler]
There is growing experimental evidence that electrons confined to two dimensions (in a semiconductor heterostructure, for instance) at low temperatures and high magnetic fields can display a plethora of partially ordered phases which have the same symmetries as classical liquid crystal phases, such as nematics and smectics. I will review the experimental evidence for these novel quantum phases of matter, discuss several analogous classical systems, and motivate some of the theoretical models for these "quantum Hall liquid crystals".
