Many-body quantum coherence and interaction blockade in Josephson-linked Bose-Einstein condensates

Abstract

We study many-body quantum coherence and interaction blockade in two Josephsonlinked Bose-Einstein condensates. We introduce universal operators for characterizing many-body coherence without limitations on the system symmetry and total particle number N . We reproduce the results for both coherence fluctuations and number squeezing in symmetric systems of… (More)
