Query: Spin squeezing and EPR entanglement of two bimodal condensates in
  state-dependent potentials   We propose and analyze a scheme to entangle the collective spin states of two
spatially separated bimodal Bose-Einstein condensates. Using a four-mode
approximation for the atomic field, we show that elastic collisions in a
state-dependent potential simultaneously create spin-squeezing in each
condensate and entangle the collective spins of the two condensates. We
investigate mostly analytically the non-local quantum correlations that arise
in this system at short times and show that Einstein-Podolsky-Rosen (EPR)
entanglement is generated between the condensates. At long times we point out
macroscopic entangled states and explain their structure. The scheme can be
implemented with condensates in state-dependent microwave potentials on an atom
chip.
