Propagating modes seem to be a generic property of systems with spin-orbit coupling. Through a rigorous Keldysh approach, we obtain the transport equations for the 2DHG, we analyze the behavior of the hole spin relaxation time, the diffusion coefficients, and the spin-charge coupled motion.", "revisions": [ { "version": "v1", "updated": "2006-01-16T21:00:09.000Z" } ], "analyses": { "keywords": [ "spin-charge propagating mode", "transport equations", "hole spin relaxation time", "cubic dispersion apart", "strongly confined two-dimensional hole gas" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
