P Viot, A Argun, G Volpe, A Imparato, L Rondoni… - Soft Matter, 2024 - pubs.rsc.org
The Brownian gyrator (BG) is often called a minimal model of a nano-engine performing a
rotational motion, judging solely upon the fact that in non-equilibrium conditions its torque …

Tunable Brownian magneto heat pump
