A mesoscopic description of radiative heat transfer at the nanoscale [PDF]

open access: yesPhysical Review Letters, 2010
We present a formulation of the nanoscale radiative heat transfer (RHT) using concepts of mesoscopic physics. We introduce the analog of the Sharvin conductance using the quantum of thermal conductance.

Heat transfer at nanoscale and boundary conditions [PDF]

open access: yesZeitschrift Fur Angewandte Mathematik Und Physik, 2022
AbstractA model of nonlocal heat transfer at nanoscale in rigid bodies is considered. Depending on the relevance of the particular interaction’s mechanism between the heat carriers and the lateral walls, three different strategies for the setting-up of the boundary conditions are analyzed, and the consequent forms of the basic fields have been obtained,
