Microwave spectroscopic studies of the bilayer electron solid states at low Landau filling in a wide quantum well
A. T. Hatke, Y. Liu, L. W. Engel +4
At the low Landau filling factor termination of the fractional quantum Hall effect (FQHE) series, two-dimensional electron systems (2DESs) exhibit an insulating phase that is…
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…
On Polar Magnetic Field Reversal and Surface Flux Transport During Solar Cycle 24
Xudong Sun, J. Todd Hoeksema, Yang Liu +1
As each solar cycle progresses, remnant magnetic flux from active regions (ARs) migrates poleward to cancel the old-cycle polar field. We describe this polarity reversal process du…
Fractional Quantum Hall Effect in Tilted Magnetic Fields
Sukret Hasdemir, Yang Liu, H. Deng +4
Magnetotransport measurements on two-dimensional electrons confined to wide GaAs quantum wells reveal a remarkable evolution of the ground state at filling factor as we til…
Composite Fermions Waltz to the Tune of a Wigner Crystal
Yang Liu, H. Deng, M. Shayegan +3
When the kinetic energy of a collection of interacting two-dimensional (2D) electrons is quenched at very high magnetic fields so that the Coulomb repulsion dominates, the electron…
Spin-Polarization of Composite Fermions and Particle-Hole Symmetry Breaking
Yang Liu, S. Hasdemir, A. Wójs +5
We study the critical spin-polarization energy () above which fractional quantum Hall states in two-dimensional electron systems confined to symmetric GaAs quantum wells…
