Strong-coupling emergence of dark states in XX central spin models

Year: 2022

Type: article

Abstract: In an XX central spin model, a particular spin interacts with a bath of other spins through a term which only couples their XY-plane components. In the presence of an arbitrarily oriented magnetic field, it is shown that certain eigenstates of this model are such that the central spin remains in a pure state, completely disentangled from the bath. Remarkably, this decoupling from the environment becomes possible only when the interaction becomes strong enough.
