Reversible temperature exchange upon thermal contact by Eugene G. Mishchenko Paul F. Pshenichka. DOI: 10.1119/1.4965292

According to a well-known principle of thermodynamics, the transfer of heat between two bodies is reversible when their temperatures are infinitesimally close. As we demonstrate, a little-known alternative exists: two bodies with temperatures different by an arbitrary amount can completely exchange their temperatures in a reversible way if split into infinitesimal parts that are brought into thermal contact sequentially.
