A nano heat engine beyond the Carnot limit
Johannes Roßnagel, Obinna Abah, Ferdinand Schmidt-Kaler +2
Heat engines extract work by running cyclically between two heat reservoirs. When the two reservoirs are thermal and at different temperatures, the maximum efficiency of the engine…

Efficiency of heat engines coupled to nonequilibrium reservoirs
Obinna Abah, Eric Lutz
We consider quantum heat engines that operate between nonequilibrium stationary reservoirs. We evaluate their maximum efficiency from the positivity of the entropy production and s…
