    "abstract": "We investigate the creation of a relative phase between two Bose-Einstein\ncondensates, initially in number states, by detection of atoms and show how the\nsystem approaches a coherent state. Two very distinct time scales are found:\none for the creation of the interference is of the order of the detection time\nfor a few single atoms and another, for the preparation of coherent states, of\nthe order of the detection time for a significant fraction of the total number\nof atoms. Approximate analytic solutions are derived and compared with exact\nnumerical results.",
