    "abstract": "Atom interferometers using Bose-Einstein condensate that is confined in a\nwaveguide and manipulated by optical pulses have been limited by their short\ncoherence times. We present a theoretical model that offers a physically simple\nexplanation for the loss of contrast and propose the method for increasing the\nfringe contrast by recombining the atoms at a different time. A simple,\nquantitatively accurate, analytical expression for the optimized recombination\ntime is presented and used to place limits on the physical parameters for which\nthe contrast may be recovered.",
