Controlling quantum coherence of a two-component Bose-Einstein condensate via an impurity atom
Zhen Li, Le-Man Kuang
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 a…

Complementarity between micro-micro and micro-macro entanglement in a Bose-Einstein condensate with two Rydberg impurities
Zhen Li, Yu Han, Le-Man Kuang
We theoretically study complementarity between micro-micro and micro-macro entanglement in a Bose-Einstein condensate with two Rydberg impurities. We investigate quantum dynamics o…
