Quantum coherence for Bose-Einstein condensates induced by an imaginary potential
Quantum coherence for Bose-Einstein condensates induced by an imaginary potential
The role of complex potentials in single-body Schr\H{o}dinger equation has been studied intensively. We study the quantum coherence for degenerate Bose gases in complex potentials, when the exchange symmetry of identical bosons is considered. For initially independent Bose-Einstein condensates, it is shown that even very weak imaginary potential can induce …
