    "abstract": "The collisional interaction in a Bose condensate represents a non-linearity\nwhich in analogy with non-linear optics gives rise to unique quantum features.\nIn this paper we apply a Monte Carlo method based on the positive P\npseudo-probability distribution from quantum optics to analyze the efficiency\nof spin squeezing by collisions in a two-component condensate. The squeezing\ncan be controlled by choosing appropiate collision parameters or by\nmanipulating the motional states of the two components.",
