Irreversibility in active matter systems: Fluctuation theorem and mutual information
We consider a Brownian particle which, in addition to being in contact with a thermal bath, is
driven by fluctuating forces which stem from active processes in the system, such as self …

Rapid-prototyping a Brownian particle in an active bath
Particles kicked by external forces to produce mobility distinct from thermal diffusion are an
iconic feature of the active matter problem. Here, we map this onto a minimal model for …

Revealing the nonequilibrium nature of a granular intruder: the crucial role of non-Gaussian behavior
The characterization of the distance from equilibrium is a debated problem in particular in
the treatment of experimental signals. If the signal is a one-dimensional time series, such a …

Periodic potential can enormously boost free-particle transport induced by active fluctuations
Active fluctuations are detected in a growing number of systems due to self-propulsion
mechanisms or collisions with an active environment. They drive the system far from …
