Query: Entanglement of two hybrid optomechanical cavities composed of BEC atoms
  under Bell detection   In this paper, firstly, we consider bipartite entanglement between each part
of an optomechanical cavity composed of one dimensional Bose-Einstein
condensate (BEC). we investigate atomic collision on the behavior of the BEC in
the week photon-atom coupling constant, and use Bogoliubov approximation for
the BEC. Secondly under above condition, we propose a scheme for entanglement
swapping protocol wich involves tripartite systems. In our investigation, we
consider a scenario where BECs, moving mirrors, and optical cavity modes are
given in a Gaussian state with a covariance matrix (CM). By applying the Bell
measurment to the output optical field modes, we show how the remote
entanglement between two BECs, two moving mirrors, and BEC-mirror modes in
different optomechanical cavity can be generated.
