Heterostructure Symmetry and the Orientation of the Quantum Hall Nematic Phases
J. Pollanen, K. B. Cooper, S. Brandsen +3
Clean two-dimensional electron systems in GaAs/AlGaAs heterostructures exhibit anisotropic collective phases, the quantum Hall nematics, at high Landau level occupancy and low temp…
Metastable Resistance Anisotropy Orientation of Two-Dimensional Electrons in High Landau Levels
K. B. Cooper, J. P. Eisenstein, L. N. Pfeiffer +1
In half-filled high Landau levels, two-dimensional electron systems possess collective phases which exhibit a strongly anisotropic resistivity tensor. A weak, but as yet unknown, r…
Observation of narrow-band noise accompanying the breakdown of insulating states in high Landau levels
K. B. Cooper, J. P. Eisenstein, L. N. Pfeiffer +1
Recent magnetotransport experiments on high mobility two-dimensional electron systems have revealed many-body electron states unique to high Landau levels. Among these are re-entra…
The Onset of Anisotropic Transport of Two-Dimensional Electrons in High Landau Levels: An Isotropic-to-Nematic Liquid Crystal Phase Transition?
K. B. Cooper, M. P. Lilly, J. P. Eisenstein +2
The recently discovered anisotropy of the longitudinal resistance of two-dimensional electrons near half filling of high Landau levels is found to persist to much higher temperatur…
Insulating and Fractional Quantum Hall States in the N=1 Landau Level
J. P. Eisenstein, K. B. Cooper, L. N. Pfeiffer +1
The observation of new insulating phases of two-dimensional electrons in the first excited Landau level is reported. These states, which are manifested as re-entrant integer quanti…
New collective states of 2D electrons in high Landau levels
J. P Eisenstein, M. P. Lilly, K. B. Cooper +2
A brief summary of the emerging evidence for a new class of collective states of two-dimensional electrons in partially occupied excited Landau levels is presented. Among the most…
