Disorder broadening of even denominator fractional quantum Hall states in the presence of a short-range alloy potential
E. Kleinbaum, Hongxi Li, N. Deng +3
We study energy gaps of the and fractional quantum Hall states in a series of two-dimensional electron gases containing alloy disorder. We found that gaps at these…
Electron-Electron Interactions and the Paired-to-Nematic Quantum Phase Transition in the Second Landau Level
K. A. Schreiber, N. Samkharadze, G. C. Gardner +5
In spite of its ubiquity in strongly correlated systems, the competition of paired and nematic ground states remains poorly understood. Recently such a competition was reported in…
Onset of Quantum Criticality in the Topological-to-Nematic Transition in a Two-dimensional Electron Gas at Filling Factor
K. A. Schreiber, N. Samkharadze, G. C. Gardner +3
Under hydrostatic pressure, the ground state of a two-dimensional electron gas at changes from a fractional quantum Hall state to the stripe phase. By measuring the energy…
Modified MBE hardware and techniques and role of gallium purity for attainment of two dimensional electron gas mobility >35 x10^6 cm^2/Vs in AlGaAs/GaAs quantum wells grown by MBE
Geoffrey C. Gardner, Saeed Fallahi, John D. Watson +1
We provide evidence that gallium purity is the primary impediment to attainment of ultra-high mobility in a two-dimensional electron gas (2DEG) in AlGaAs/GaAs heterostructures grow…
Observation of a transition from a topologically ordered to a spontaneously broken symmetry phase
N. Samkharadze, K. A. Schreiber, G. C. Gardner +3
Until the late 1980s, phases of matter were understood in terms of Landau's symmetry breaking theory. Following the discovery of the quantum Hall effect the introduction of a secon…
