Interlayer Transport in Bilayer Quantum Hall Systems
Enrico Rossi, Alvaro S. Núñez, A. H. MacDonald
Bilayer quantum Hall systems have a broken symmetry ground state at filling factor which can be viewed either as an excitonic superfluid or as a pseudospin ferromagnet. We pr…
Spin Transfer Without Spin Conservation
Alvaro S. Núñez, A. H. MacDonald
We propose a general theory of the spin-transfer effects that occur when current flows through inhomogeneous magnetic systems. Our theory does not rest on an appeal to conservation…
Collective transport properties of bilayer-quantum-Hall excitonic condensates
Allan H. MacDonald, Anton A. Burkov, Yogesh N. Joglekar +1
Double-layer electron systems in the quantum Hall regime have excitonic condensate ground states when the layers are close together and the total Landau level filling factor is clo…
First Principles Calculation of Anomalous Hall Conductivity in Ferromagnetic bcc Fe
Yugui Yao, L. Kleinman, A. H. MacDonald +5
We perform a first principles calculation of the anomalous Hall effect in ferromagnetic bcc Fe. Our theory identifies an intrinsic contribution to the anomalous Hall conductivity a…
Optical spin transfer in ferromagnetic semiconductors
J. Fernández-Rossier, Alvaro S. Núñez, M. Abolfath +1
Circularly polarized laser pulses that excite electron-hole pairs across the band gap of (III,Mn)V ferromagnetic semiconductors can be used to manipulate and to study collective ma…
Ferromagnetism in (III,Mn)V Semiconductors
J. König, J. Schliemann, T. Jungwirth +1
In this review article we briefly summarize the main experimental properties of (III,Mn)V ferromagnets and outline several different but related approaches that have been explored…
