Finite-temperature fidelity and von Neumann entropy in the honeycomb spin lattice with quantum Ising interaction
Yan-Wei Dai, Qian-Qian Shi, Sam Young Cho +2
The finite temperature phase diagram is obtained for an infinite honeycomb lattice with spin- Ising interaction by using thermal-state fidelity and von Neumann entropy bas…
Geometric entanglement and quantum phase transitions in two-dimensional quantum lattice models
Qian-Qian Shi, Hong-Lei Wang, Sheng-Hao Li +3
Geometric entanglement(GE), as a measure of multipartite entanglement, has been investigated as a universal tool to detect phase transitions in quantum many-body lattice models. We…
Evidence for a new symmetry breaking mechanism reorienting quantum Hall nematics
Q. Shi, M. A. Zudov, J. D. Watson +2
We report on the effect of in-plane magnetic field on stripe phases in higher () Landau levels of a high-mobility 2D electron gas. In accord with previous stud…
Resistively detected high-order magnetoplasmons in a high-quality 2D electron gas
Q. Shi, M. A. Zudov, L. N. Pfeiffer +3
We report on high-order magnetoplasmon resonances detected in photoresistance in high-mobility GaAs quantum wells. These resonances manifest themselves as a series of photoresistan…
Microwave Photoresistance in an Ultrahigh Quality GaAs Quantum Well
Q. Shi, S. A. Studenikin, M. A. Zudov +3
The temperature dependence of microwave-induced resistance oscillations (MIRO), according to the theory, originates from electron-electron scattering. This scattering affects both…
Reorientation of quantum Hall stripes within a partially filled Landau level
Q. Shi, M. A. Zudov, J. D. Watson +2
We investigate the effect of the filling factor on transport anisotropies, known as stripes, in high Landau levels of a two-dimensional electron gas. We find that at certain in-pla…
