Abstract

A global quantitative picture of the phonon-induced two-electron spin relaxation in GaAs double quantum dots is presented using highly accurate numerics. Wide regimes of interdot coupling, magnetic field magnitude and orientation, and detuning are explored in the presence of a nuclear bath. Mostimportant, the giant magnetic anisotropy of the singlet-triplet relaxation can be controlled by ...
