Controlling quantum coherence of a two-component Bose–Einstein condensate via an impurity atom

We propose a scheme to control quantum coherence of a two-component Bose–Einstein condensate (BEC) by a single impurity atom immersed in the BEC. We show that the single impurity atom can act as a single-atom valve (SAV) to control quantum coherence of the two-component BEC. It is demonstrated that...
