Nonequilibrium electron spin polarization in a double quantum dot. Lande mechanism
arXiv:cond-mat/0508566 · doi:10.1103/PhysRevB.74.035325
Abstract
In moderately strong magnetic fields, the difference in Lande g-factors in each of the dots of a coupled double quantum dot device may induce oscillations between singlet and triplet states of the entangled electron pair and lead to a nonequilibrium electron spin polarization. We will show that this polarization may partially survive the rapid inhomogeneous decoherence due to random nuclear magnetic fields.
