8 Jun 2006 | | Subject: | Mesoscopic Systems and Quantum Hall Effect | | Abstract: | How does an initially homogeneous spin-polarization in a confined two-dimensional electron gas with Rashba spin-orbit coupling evolve in time? How does the relaxation time depend on system size? We study these questions for systems of a size that is much larger than the Fermi wavelength, but comparable and even shorter than the spin relaxation length. Depending on the confinement spin-relaxation may become faster or slower than in the bulk. An initially homogeneously polarized spin system evolves into a spiral pattern. | | Source: | arXiv, cond-mat/0606209 | | Services: | Forum | Review | PDF | Favorites | |
