Diffusive contact between randomly driven colloidal suspensions
Galor Geva, Tamir Admon, Maayan Levin +1
We study the relaxation process of two driven colloidal suspensions in diffusive contact to a steady state, similar to thermalization. We start by studying a single suspension, sub…
The fluctuation-dissipation relation holds for a macroscopic tracer in an active bath
Dima Boriskovsky, Benjamin Lindner, Yael Roichman
The fluctuation-dissipation relation (FDR) links thermal fluctuations and dissipation at thermal equilibrium through temperature. Extending it beyond equilibrium conditions in purs…
Nonequilibrium Probability Currents in Optically-Driven Colloidal Suspensions
Samudrajit Thapa, Daniel Zaretzky, Ron Vatash +4
In the absence of directional motion it is often hard to recognize athermal fluctuations. Probability currents provide such a measure in terms of the rate at which they enclose are…
Resetting as a swift equilibration protocol in an anharmonic potential
Rémi Goerlich, Tommer D. Keidar, Yael Roichman
We present and characterize a method to accelerate the relaxation of a Brownian object between two distinct equilibrium states. Instead of relying on a deterministic time-dependent…
