title: Exact time-averaged thermal conductance for small systems: comparison between direct calculation and Green-Kubo formalism.
abstract: In this paper, we study exactly the thermal conductance for a low dimensional system represented by two coupled massive Brownian particles, both directly and via a Green-Kubo expression. Both approaches give exactly the same result. We also obtain exactly the steady-state probability distribution for that system by means of time averaging.
