Query: Phononic heat transport in nanomechanical structures: steady-state and
  pumping   We study the heat transport due to phonons in nanomechanical structures using
a phase space representation of non-equilibrium Green's functions. This
representation accounts for the atomic degrees of freedom making it
particularly suited for the description of small (molecular) junctions systems.
We show that for the steady state limit our formalism correctly recovers the
heuristic Landauer-like heat conductance for a quantum coherent molecular
system coupled to thermal reservoirs. We find general expressions for the
non-stationary heat current due to an external periodic drive. In both cases we
discuss the quantum thermodynamic properties of the systems. We apply our
formalism to the case of a diatomic molecular junction.
