In this paper we generate some new classes of entangled states of a two-mode Bose-Einstein condensate (BEC) in the presence of two- and three-body elastic as well as mode-exchange collisions. After introducing the general form of the time evolved state, various classes of entangled states are generated. Depending on the tunneling strength constants, two-, three- and four-partite entangled states are generated. Considering three-particle collision dramatically changes the generated entangled states. Moreover, in particular cases, the resulted states are non-entangled. The degree of entanglement for two-partite entangled states can be tuned via the number of BEC atoms i.e., the corresponding concurrence tends to its maximum value by increasing the number of atoms in the system.
Keywords: Two-mode Bose-Einstein condensate, entangled state, interatom collisions, tunnel-coupled.
