Abstract: Cold-atom interferometers with optical splitting and recombination useoff-resonant laser beams to split a cloud of Bose-Einstein condensate BECinto two clouds that travel along different paths and are then recombined againusing optical beams. After the recombination, the BEC in general populates boththe cloud at rest and the moving clouds. Measuring relative number of atoms ineach of these clouds yields information about the relative phase shiftaccumulated by the atoms in the two moving clouds during the interferometriccycle. We derive the expression for the probability of finding any given numberof atoms in each of the clouds, discuss features of the probability densitydistribution, analyze its dependence on the relative accumulated phase shift asa function of the strength of the interatomic interactions, and compare ourresults with experiment.
