Static and dynamic properties of crystalline phases of two-dimensional electrons in a strong magnetic field
A. M. Ettouhami, F. D. Klironomos, Alan T. Dorsey
We study the cohesive energy and elastic properties as well as normal modes of the Wigner and bubble crystals of the two-dimensional electron system (2DES) in higher Landau levels.…
Anisotropic states of two-dimensional electrons in high magnetic fields
A. M. Ettouhami, C. B. Doiron, F. D. Klironomos +2
We study the collective states formed by two-dimensional electrons in Landau levels of index near half-filling. By numerically solving the self-consistent Hartree-Fock (HF…
Possible new bubble phases of two-dimensional electrons in higher Landau levels
A. M. Ettouhami, F. D. Klironomos, A. T. Dorsey
We argue that, due to the specific form of the interaction potential between electronic guiding centers, a bubble crystal (BC) with basis may be energetically more favorable than t…
Tunneling between two-dimensional electron systems in a high magnetic field: role of interlayer interactions
F. D. Klironomos, A. T. Dorsey
We calculate the tunneling current for a bilayer quantum Hall system in the interlayer incoherent regime. In order to capture the strong correlation effects we model the layers as…
Tunneling between bilayer quantum Hall structures in a strong magnetic field
F. D. Klironomos, A. T. Dorsey
We calculate the tunneling current in a quantum Hall bilayer system in the strong magnetic field limit. We model the bilayer electron system as two Wigner crystals coupled through…
Fingering of Electron Droplets in Nonuniform Magnetic Fields
Taylor L. Hughes, A. D. Klironomos, Alan T. Dorsey
A semiclassical analysis of a two-dimensional electron droplet in a high, nonuniform magnetic field predicts that the droplet will form ``fingered'' patterns upon increasing the nu…
Theory of Quantum Hall Nematics
Leo Radzihovsky, Alan T. Dorsey
Transport measurements on two dimensional electron systems in moderate magnetic fields suggest the existence of a spontaneously orientationally-ordered, compressible liquid state.…
Disclination Unbinding Transition in Quantum Hall Liquid Crystals
C. Wexler, Alan T. Dorsey
We derive the the long-wavelength elastic theory for the quantum Hall smectic state starting from the Hartree-Fock approximation. Dislocations in this state lead to an effective ne…
Physics on the edge: contour dynamics, waves and solitons in the quantum Hall effect
C. Wexler, Alan T. Dorsey
We present a theoretical study of the excitations on the edge of a two-dimensional electron system in a perpendicular magnetic field in terms of a contour dynamics formalism. In pa…
Solitons on the edge of a two-dimensional electron system
C. Wexler, Alan T. Dorsey
We present a study of the excitations of the edge of a two-dimensional electron droplet in a magnetic field in terms of a contour dynamics formalism. We find that, beyond the usual…
