1 May 2003 | | Subject: | Materials Science; Statistical Mechanics | cond-mat.mtrl-sci cond-mat.stat-mech | | Abstract: | An effective spin relaxation mechanism that leads to electron spin decoherence in a quantum dot is proposed. In contrast to the common calculations of spin-flip transitions between the Kramers doublets, we take into account a process of phonon-mediated fluctuation in the electron spin precession and subsequent spin phase diffusion. Specifically, we consider modulations in the longitudinal g-factor and hyperfine interaction induced by the phonon-assisted transitions between the lowest electronic states. Prominent differences in the temperature and magnetic field dependence between the proposed mechanisms and the spin-flip transitions are expected to facilitate its experimental verification. Numerical estimation demonstrates highly efficient spin relaxation in typical semiconductor quantum dots. | | Source: | arXiv, cond-mat/0305005 | | Services: | Forum | Review | PDF | Favorites | |
