Atom-number squeezing and bipartite entanglement of two-component Bose-Einstein condensates: analytical results
arXiv:0912.0444 · doi:10.1088/0953-4075/43/4/045301
Abstract
We investigate spin dynamics of a two-component Bose-Einstein condensates with weak Josephson coupling. Analytical expressions of atom-number squeezing and bipartite entanglement are presented for atom-atom repulsive interactions. For attractive interactions, there is no number squeezing; however, the squeezing parameter is still useful to recognize the appearance of Schrödinger's cat state.
