We consider a one-dimensional potential trap that connects two reservoirs containing cold Bose atoms. The thermal current and single-particle bosonic Green's functions are calculated under nonequilibrium conditions. The bosonic statistics leads to a Luttinger liquid state with a nonlinear spectrum of collective modes. This results in the suppression of thermal current at low temperatures and affects the single-particle Green's functions.
