Dissipationless Spin Current in Anisotropic p-Doped Semiconductors
Bogdan A. Bernevig, JiangPing Hu, Eran Mukamel +1
Recently, dissipationless spin current has been predicted for the p-doped semiconductors with spin-orbit coupling. Here we investigate the effect of spherical symmetry breaking on…
The Eight Dimensional Quantum Hall Effect and the Octonions
B. A. Bernevig, J. P. Hu, N. Toumbas +1
We construct a generalization of the quantum Hall effect where particles move in an eight dimensional space under an SO(8) gauge field. The underlying mathematics of this particle…
Effective field theory description of the higher dimensional quantum Hall liquid
B. Andrei Bernevig, Chyh-Hong Chern, Jiang-Ping Hu +2
We derive an effective topological field theory model of the four dimensional quantum Hall liquid state recently constructed by Zhang and Hu. Using a generalization of the flux att…
Spinon Attraction in Spin-1/2 Antiferromagnetic Chains
B. A. Bernevig, D. Giuliano, R. B. Laughlin
We derive the representation of the two-spinon wavefunction for the Haldane-Shastry model in terms of the spinon coordinates. This result allows us to rigorously analyze spinon int…
