    "abstract": "We present a scheme to prepare generalized coherent states in a system with\ntwo species of Bose-Einstein condensates. First, within the two-mode\napproximation, we demonstrate that a Schrodinger cat-like can be dynamically\ngenerated and, by controlling the Josephson-like coupling strength, the number\nof coherent states in the superposition can be varied. Later, we analyze\nnumerically the dynamics of the whole system when interspecies collisions are\ninhibited. Variables such as fractional population, Mandel parameter and\nvariances of annihilation and number operators are used to show that the\nevolved state is entangled and exhibits sub-Poisson statistics.",
