Two-spin dephasing by electron-phonon interaction in semiconductor double quantum dots
Two-spin dephasing by electron-phonon interaction in semiconductor double quantum dots
We study electron-phonon interaction induced decoherence between two-electron singlet and triplet states in a semiconductor double quantum dot using a spin-boson model. We investigate the onset and time evolution of this dephasing, and study its dependence on quantum dot parameters such as dot size and double dot separations, as well …
