Cyclotron Orbits of Composite Fermions in the Fractional Quantum Hall Regime
Insun Jo, Hao Deng, Yang Liu +4
We study a bilayer GaAs hole system that hosts two distinct many-body phases at low temperatures and high perpendicular magnetic fields. The higher-density (top) layer develops a F…
Interaction-induced Interlayer Charge Transfer in the Extreme Quantum Limit
H. Deng, Y. Liu, I. Jo +4
An interacting bilayer electron system provides an extended platform to study electron-electron interaction beyond single layers. We report here experiments demonstrating that the…
Tuning of Fermi Contour Anisotropy in GaAs (001) 2D Holes via Strain
Insun Jo, M. A. Mueed, L. N. Pfeiffer +5
We demonstrate tuning of the Fermi contour anisotropy of two-dimensional (2D) holes in a symmetric GaAs (001) quantum well via the application of in-plane strain. The ballistic tra…
Transference of Fermi Contour Anisotropy to Composite Fermions
Insun Jo, K. A. Villegas Rosales, M. A. Mueed +6
There has been a surge of recent interest in the role of anisotropy in interaction-induced phenomena in two-dimensional (2D) charged carrier systems. A fundamental question is how…
Signatures of an annular Fermi sea
Insun Jo, Yang Liu, L. N. Pfeiffer +4
We report Shubnikov-de Haas oscillations measurements revealing experimental signatures of an annular Fermi sea that develops near the energy band edge of the excited subband of tw…
Determination of the Fermi Contour and Spin-polarization of Composite Fermions via Ballistic Commensurability Measurements
D. Kamburov, M. A. Mueed, I. Jo +6
We report ballistic transport commensurability minima in the magnetoresistance of composite fermions (CFs). The CFs are formed in high-quality two-dimensional electron syst…
