Fluctuation Theorem for Heat Flow

International Journal of Thermophysics, 2001
Thermal conduction in a classical many-body system which is in contact with two isothermal reservoirs maintained at different temperatures is considered. The probability that when observed for a finite time, the heat flux of a finite system flows in the reverse direction to that required by the Second Law of Thermodynamics is calculated from first ...

ON HEAT FLOW AND NON-RECIPROCITY

International Journal of Modern Physics B, 2001
Heat transfer properties in non-reciprocal systems are discussed. An ideal experiment employing microwave or optical isolators is considered in order to investigate the possibility for a spontaneous transfer of energy between two black-bodies at common temperatures.
