title: Phonon-induced decoherence of spin-orbit-driven coherent oscillations in a single InGaAs quantum dot.
abstract: The effect of direct spin-phonon interactions on spin-orbit-driven coherent oscillations in a single quantum dot proposed by Debald and Emary (2005 Phys. Rev. Lett. 94 226803) is investigated theoretically in terms of the perturbation treatment based on a unitary transformation. It is shown that the decoherence rate induced by acoustic phonons strongly depends on the spin-orbit coupling strength, the magnetic field strength and the dot size.
