On the transport between condensed phases
N Angelescu, M. Bundaru
Abstract
An exactly solvable model for the particle transport between two reservoirs of non-interacting Bose particles through a microscopic tunnelling junction is studied. The analysis covers the whole range of temperatures and densities of the reservoirs, and the particle and energy flows between the reservoirs are calculated in closed form. In particular, in the case, when Bose–Einstein condensation is present, their dependence on the phase difference of the condensates is established.
