We investigate the quantum interference between two Bose-Einstein condensatesformed in small atomic samples composed of a few thousand atoms both byimposing Bose broken gauge symmetry from the outset and also using an explicitmodel of atomic detection. In the former case we show that the macroscopic wavefunction collapses and revives in time, and we calculate the characteristictimes for current experiments. Collapses and revivals are also predicted in theinterference between two Bose-Einstein condensates which are initially in Fockstates, a relative phase between the condensates being established via atomicdetections corresponding to uncertainty in the number difference between them.Comment: 17 pages, 3 PostScript figure, submitted to PR
