Liquid-Crystal State of Quantum Hall Effects
arXiv:cond-mat/0501507
Abstract
At filling factor , odd integer, I present variational ground-state and excited-state wave functions, of two-dimensional electron system with homogeneous ion background, that show the condensation into a liquid-crystal state. For , the ground-state energy per electron is substantially lower than the Laughlin one, for uniform liquid state.
