Description

Symmetries constrain dynamics. We test this fundamental physical principle, experimentally and by molecular dynamics simulations, for a hot Janus swimmer operating far from thermal equilibrium. Our results establish scalar and vectorial steady-state fluctuation theorems and a thermodynamic uncertainty relation that link the fluctuating particle current to its virtual entropy production at an effective temperature. A Markovian minimal model elucidates the underlying non-equilibrium physics. Gianmaria Falasco, Richard Pfaller, Andreas P.
