Quantum theory of quantum Hall smectics
We propose a quantum stripe ~smectic! coupled-Luttinger-liquid model for the anisotropic states which occur in two-dimensional electron systems with high-index partial Landau-level filling, n*5n2@n# . Perturbative renormalization-group calculations establish that interaction terms neglected in this model are relevant —probably driving the system into an anisotropic Wigner crystal—but for 0.4&n*...
متن کاملQuantum theory of bilayer quantum Hall smectics
Mean-field theory predicts that bilayer quantum Hall systems at odd integer total filling factors can have stripe ground states, in which the top Landau level is occupied alternately by electrons in one of the two layers. We report on an analysis of the properties of these states based on a coupled-Luttinger-liquid description that is able to account for quantum fluctuations of charge-density a...
متن کاملHydrodynamics of the quantum hall smectics.
We propose a dynamical theory of the stripe phase arising in a two-dimensional electron liquid near half-integral fillings of high Landau levels. The system is modeled as a novel type of a smectic liquid crystal with Lorentz force dominated dynamics. We calculate the structure factor, the dispersion relation of the collective modes, and their intrinsic attenuation rate. We show that thermal flu...
متن کاملNon-linear Transport in Quantum-Hall Smectics
Recent transport experiments have established that two-dimensional electron systems with high-index partial Landau level filling, ν∗ = ν − [ν], have ground states with broken orientational symmetry. In a mean-field theory, the broken symmetry state consists of electron stripes with local filling factor [ν] + 1, separated by hole stripes with filling factor [ν]. We have recently developed a theo...
متن کاملAlgebras in Quantum Hall Theory
We show that U(∞) symmetry transformations of the noncommutative field theory in the Moyal space are generated by a combination of twoW1+∞ algebras in the Landau problem. Geometrical meaning of this infinite symmetry is illustrated by examining the transformations of an invariant subgroup on the noncommutative solitons, which generate deformations and boosts of solitons. In particular, we find ...
