Entanglement in Spin Waves with Binary Dipolar Atoms in a 2D Optical
Lattice
H. T. Ng, K. Burnett
abstract: We study the area-dependent entropy and two-site entanglement in the spin
waves with binary interacting dipolar Bose-Einstein condensates in a 2D optical
lattice. The two species condensates at each site behave like an ensemble of
spin-half particles with the interaction to its nearest neighbors and next
nearest neighbors. We show that the ground state of a Bose-Einstein condensate
lattice with nearest-neighbor and next-nearest-neighbor interactions exhibits
spin wave and can be mapped into a harmonic lattice. The critical behavior of
the area-dependent entropy and two-site entanglement is examined in the
vicinity of a quantum phase transition.
