Intrinsic Spin-Hall Effect in n-Doped Bulk GaAs
B. Andrei Bernevig, Shou-Cheng Zhang
We show that the bulk Dresselhauss () spin-orbit coupling term leads to an intrinsic spin-Hall effect in n-doped bulk GaAs, but without the appearance of uniform magnetization…
Intrinsic Spin Hall Effect in the Two Dimensional Hole Gas
B. Andrei Bernevig, Shou-Cheng Zhang
We show that two types of spin-orbit coupling in the 2 dimensional hole gas (2DHG), with and without inversion symmetry breaking, contribute to the intrinsic spin Hall effect\cite{…
Maxwell Equation for the Coupled Spin-Charge Wave Propagation
B. Andrei Bernevig, Xiaowei Yu, Shou-Cheng Zhang
We show that the dissipationless spin current in the ground state of the Rashba model gives rise to a reactive coupling between the spin and charge propagation, which is formally i…
On attraction between particles with fractionalized quantum numbers in one-dimensional devices
Bogdan A. Bernevig, Domenico Giuliano, Robert B. Laughlin
We make some comments about the results we obtained in Phys. Rev. Lett. 86,3392(2001), and in Phys. Rev. Lett.87, 177206 (2001), and show that the conclusion of a recent paper [con…
Piezo-Magneto-Electric Effects in p-Doped Semiconductors
B. Andrei Bernevig, Oskar Vafek
We predict the appearance of a uniform magnetization in strained three dimensional p-doped semiconductors with inversion symmetry breaking subject to an external electric field. We…
Spin Splitting and Spin Current in Strained Bulk Semiconductors
B. Andrei Bernevig, Shou-Cheng Zhang
We present a theory for two recent experiments in bulk strained semiconductors \cite{kato1, kato2} and show that a new, previously overlooked, strain spin-orbit coupling term may p…
On the Nature of Spin Currents
B. A. Bernevig
Full expressions for finite frequency spin and charge conductivity in Rashba and Luttinger type systems are given. Whereas in the Rashba Hamiltonian the spin conductivity has the s…
Holonomic Quantum Computing Based on the Stark Effect
B. A. Bernevig, S. C. Zhang
We propose a spin manipulation technique based entirely on electric fields applied to acceptor states in -type semiconductors with spin-orbit coupling. While interesting in its…
