Thermodynamic bound on heat to power conversion

Abstract

In systems described by the scattering theory, there is an upper bound, lower than Carnot, on the efficiency of steady-state heat to work conversion at a given output power. We show that interacting systems can overcome such bound and saturate, in the thermodynamic limit, the much more favorable linear-response bound. This result is rooted in the possibility for interacting systems to achieve the Carnot efficiency at the thermodynamic limit without delta-energy filtering, so that large efficiencies can be obtained without greatly reducing power.

arXiv comment11 pages, 11 figures, added an illustrative example in two dimensions and discussed the bound on efficiency for a given cooling power
