    "abstract": "We study the quantum dynamics of a two-mode Bose-Einstein condensate in a\ntime-dependent symmetric double-well potential using analytical and numerical\nmethods. The effects of internal degrees of freedom on the visibility of\ninterference fringes during a stage of ballistic expansion are investigated\nvarying particle number, nonlinear interaction sign and strength as well as\ntunneling coupling. Expressions for the phase resolution are derived and the\npossible enhancement due to squeezing is discussed. In particular, the role of\nthe superfluid - Mott insulator cross-over and its analog for attractive\ninteractions is recognized.",
