The Hungry Daemon: An energy-harvesting active particle must obey the Second Law of Thermodynamics
Simon Bienewald, Diego Marcel Fieguth, James R. Anglin
Thought experiments like Maxwell's Demon or the Feynman-Smoluchowski Ratchet can help in pursuing the microscopic origin of the Second Law of Thermodynamics. Here we present a more…

Friction Induced Energy Gain
Diego M Fieguth
In this work we show how friction enables a non-linear energy transfer in a slow-fast Hamiltonian system. We first introduce a paradigmatic system consisting of a weakly coupled fa…

Hamiltonian active particles in an environment
Timo Eichmann, Diego Fieguth, Daniel Brady +1
We examine a Hamiltonian system which represents an active Brownian particle that can move against an external force by drawing energy from an internal depot while immersed in a no…
