Abstract

We investigate quantum entanglement and spin squeezing of two species Bose-Einstein condensates. By the rotating-wave approximation, we obtain the effective Hamiltonian and the wave function of the system. It’s shown that more entanglement and squeezing may be achieved by increasing the population difference of particles.
