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…
Fabrication of Electronic Fabry-Perot Interferometer in the Quantum Hall Regime
Sanghun An, Simas Glinskis, Woowon Kang +4
A fabrication method for electronic quantum Hall Fabry-Perot interferometers (FPI) is presented. Our method uses a combination of e-beam lithography and low-damage dry-etching to p…
Unusual Hall Effect Anomaly in MnSi Under Pressure
Minhyea Lee, W. Kang, Y. Onose +2
We report the observation of a highly unusual Hall current in the MnSi in an applied pressure P = 6-12 kbar. The Hall conductivity displays a distinctive step-wise field profile qu…
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…
