Quantum Correlations Among Superradiant Bose–Einstein Condensate Atoms

Abstract

Quantum correlations among atoms in superradiant Bose–Einstein condensates are discussed. It is shown that atoms in the superradiant atomic condensate can exhibit continuous variable quantum entanglement analogous to Einstein–Podolsky–Rosen (EPR)type quantum correlations. Comparison to quantum entanglement in the Dicke model in thermal equilibrium is provided.
