Abstract: We demonstrate, both from a theoretical and an experimental point of view, the possibility of realizing a weak coupling between two Bose-Einstein condensates trapped in different Zeeman states. The weak coupling drives macroscopic quantum oscillations between the condensate populations and the observed current-phase dynamics is described by generalized Josephson equations. In order to highlight the superfluid nature of the oscillations, we investigate the response of a 87Rb non-condensate (thermal) gas in the same conditions, showing that the thermal oscillations damp more quickly than those of the condensate.
