Abstract

Active reservoirs refer to a special class of nonequilibrium reservoirs, which are made of self-propelled particles like bacteria or Janus beads. I will discuss two interesting aspects of such reservoirs. The stationary relaxation dynamics of a harmonically trapped probe particle shows qualitatively different features from equilibrium. I will show that this can be attributed to an additional force, that emerges when the bath degrees are averaged over a NESS conditioned to a certain probe position. In the second part, I will discuss what happens when two active reservoirs are connected by a harmonic chain, resulting in anomalous energy transport.
