Quantum 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 کاملQuantum 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 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 کاملTheory of activated transport in bilayer quantum Hall systems.
We analyze the transport properties of bilayer quantum Hall systems at total filling factor nu=1 in drag geometries as a function of interlayer bias, in the limit where the disorder is sufficiently strong to unbind meron-antimeron pairs, the charged topological defects of the system. We compute the typical energy barrier for these objects to cross incompressible regions within the disordered sy...
