    "abstract": "The relative phase between two uncoupled BE condensates tends to attain a\nspecific value when the phase is measured. This can be done by observing their\ndecay products in interference. We discuss exactly solvable models for this\nprocess in cases where competing observation channels drive the phases to\ndifferent sets of values. We treat the case of two modes which both emit into\nthe input ports of two beam splitters, and of a linear or circular chain of\nmodes. In these latter cases, the transitivity of relative phase becomes an\nissue.",
