Thermal ratchet effect in confining geometries
Viktor Holubec, Artem Ryabov, Mohammad Hassan Yaghoubi +4
Stochastic model of the Feynman-Smoluchowski ratchet is proposed and solved using generalization of the Fick-Jacobs theory. The theory fully captures nonlinear response of the ratc…

Maximum efficiency of steady-state heat engines at arbitrary power
Artem Ryabov, Viktor Holubec
We discuss the efficiency of a heat engine operating in a nonequilibrium steady state maintained by two heat reservoirs. Within the general framework of linear irreversible thermod…

Maximum Efficiency of Low-Dissipation Heat Engines at Arbitrary Power
Viktor Holubec, Artem Ryabov
We investigate maximum efficiency at a given power for low-dissipation heat engines. Close to maximum power, the maximum gain in efficiency scales as a square root of relative loss…
