Phonon-Mediated Electron-Spin Phase Diffusion in a Quantum Dot
Phonon-Mediated Electron-Spin Phase Diffusion in a Quantum Dot
An effective spin relaxation mechanism that leads to electron spin decoherence in a quantum dot is proposed. In contrast with 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 preces-sion and subsequent spin phase diffusion. Specifically, …
