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…
Fermi liquid behavior of metallic 2D holes at high temperatures
Xuan P. A. Gao, A. P. Mills, A. P. Ramirez +2
The resistivity of high mobility dilute 2D holes in GaAs exhibits a peak at a certain temperature in zero magnetic field(=0). In the regime where d/d0,…
Observation of Apparently Zero-Conductance States in Corbino Samples
C. L. Yang, M. A. Zudov, T. A. Knuuttila +3
Using Corbino samples we have observed oscillatory conductance in a high-mobility two-dimensional electron system subjected to crossed microwave and magnetic fields. On the stronge…
Microwave Resonance of 2D Wigner Crystal around integer Landau fillings
Yong P. Chen, R. M. Lewis, L. W. Engel +4
We have observed a resonance in the real part of the finite frequency diagonal conductivity using microwave absorption measurements in high quality 2D electron systems near {\em in…
