Exchange energy and generalized polarization in the presence of spin-orbit coupling in two dimensions | | S. Chesi

15 Jan 2007 | | Subject: | Mesoscopic Systems and Quantum Hall Effect | | Abstract: | We discuss a general form of the exchange energy for a homogeneous system of interacting electrons in two spatial dimensions which is particularly suited in the presence of a generic spin-orbit interaction. The theory is best formulated in terms of a generalized fractional electronic polarization. Remarkably we find that a net generalized polarization does not necessarily translate into an increase in the magnitude of the exchange energy, a fact that in turn favors unpolarized states. Our results account qualitatively for the findings of recent experimental investigations. | | Source: | arXiv, cond-mat/0701355 | | Services: | Forum | Review | PDF | Favorites | |
