Quantum Hall Liquid Crystals
Michael M. Fogler
In this report we summarize a recent progress in exploration of correlated two-dimensional electron states in partially filled high Landau levels. At a mean-field Hartree-Fock leve…
Stripe and bubble phases in quantum Hall systems
Michael M. Fogler
We present a brief survey of the charge density wave phases of a two-dimensional electron liquid in moderate to weak magnetic fields where several higher Landau levels are occupied…
Effective theory of incompressible quantum Hall liquid crystals
Michael M. Fogler
I propose an effective theory of zero-temperature phases of the quantum Hall stipes: a smectic phase where the stripes are static and a novel quantum nematic phase where the positi…
Low-frequency dynamics of disordered XY spin chains and pinned density waves: from localized spin waves to soliton tunneling
Michael M. Fogler
A long-standing problem of the low-energy dynamics of a disordered XY spin chain is re-examined. The case of a rigid chain is studied where the quantum effects can be treated quasi…
