We consider an exactly soluble model of two Bose-Einstein condensates with a Joseph-son-type of coupling. Its equilibrium states are explicitly found showing condensation and spontaneously broken gauge symmetry. It is proved that the total number and total phase uctuation operators, as well as the relative number and relative current uctuation operators… (More)
