Using deformed boson algebra,we study the property of two-mode coherent states in noncommutative phase space.When a two-mode field evolves in the noncommutative phase space,it can acquire an extra θ-dependent phase c...
We discuss the dynamics of Bose-Einstein condensates in a double-well potential subject to decoherenee (or particle loss). Starting from the full many-body dynamics described by the master equation, an effective Gro...
