Particle-Hole Symmetry and the Fractional Quantum Hall Effect in the Lowest Landau Level
W. Pan, W. Kang, M. P. Lilly +5
We report on detailed experimental studies of a high-quality heterojunction insulated-gate field-effect transistor (HIGFET) to probe the particle-hole symmetry (PHS) of the FQHE st…
Berry Phase and Anomalous Transport of the Composite Fermions at the Half-Filled Landau Level
W. Pan, W. Kang, K. W. Baldwin +3
The fractional quantum Hall effect (FQHE) in two-dimensional electron system (2DES) is an exotic, superfluid-like matter with an emergent topological order. From the consideration…
Tunneling between Two Quantum Hall Droplets
Inseok Yang, Woowon Kang, Loren Pfeiffer +2
We report on tunneling experiment between two quantum Hall droplets separated by a nearly ideal tunnel barrier. The device is produced by cleaved edge overgrowth that laterally jux…
Quantum Hall line junction with impurities as a multi-slit Luttinger liquid interferometer
I. Yang, W. Kang, L. N. Pfeiffer +4
We report on quantum interference between a pair of counterpropagating quantum Hall edge states that are separated by a high quality tunnel barrier. Observed Aharonov-Bohm oscillat…
Cascade of Quantum Phase Transitions in Tunnel-Coupled Edge States
I. Yang, W. Kang, K. W. Baldwin +2
We report on the cascade of quantum phase transitions exhibited by tunnel-coupled edge states across a quantum Hall line junction. We identify a series of quantum critical points b…
Metamorphosis of the Quantum Hall Ferromagnet at
Michelle Chen, Woowon Kang, Werner Wegscheider
We report on the dramatic evolution of the quantum Hall ferromagnet in the fractional quantum Hall regime at filling. A large enhancement in the characteristic timescale g…
