We consider the systematic force on a heavy probe induced by interaction with an overdamped diffusive medium where particles undergo a rotating force around a fixed center. The stiffness matrix summarizes the stability of the probe around that center, where the induced force vanishes. We prove that the introduction of the rotational force in general enhances the stability of that point (and may turn it from unstable to stable), starting at second order in the nonequilibrium amplitude.

Stabilization in the Eye of a Cyclone

We consider the systematic force on a heavy probe induced by interaction with an overdamped diffusive medium where particles undergo a rotating force around a fixed center. The stiffness matrix

Driving-induced stability with long-range effects

We give a sufficient condition under which a steady nonequilibrium driving in the form of a rotational force on medium particles stabilizes an immersed slow probe in the rotation center. We

The induced motion of a probe coupled to a bath with random resettings

We consider a probe linearly coupled to the center of mass of a nonequilibrium bath. We study the induced motion on the probe for a model where a resetting mechanism is added to an overdamped bath

How Statistical Forces Depend on the Thermodynamics and Kinetics of Driven Media.

It is shown that statistical forces for nonequilibrium media are generally nonadditive, in contrast with the equilibrium situation, and put serious constraints on any formulation of nonequ equilibrium steady state thermodynamics.

Curvature-induced activation of a passive tracer in an active bath.

It is found that even very small amounts of curvature are sufficient for the active bath to impart directed motion to the tracer, which results in its effective activation and suggests new ways of controlling the transport properties of passive tracers in an active medium by carefully tailoring their geometry.

Active Particles with Soft and Curved Walls: Equation of State, Ratchets, and Instabilities.

The pressure exerted by an active fluid of spherical particles on general boundaries in two dimensions is studied and an equation of state is recovered upon a proper spatial averaging despite the nonuniform pressure along curved walls.

Statistical forces from close-to-equilibrium media

We discuss the physical meaning and significance of statistical forces on quasi-static probes in first order around detailed balance for driven media. Exploiting the quasi-static energetics and the

Rigidity generation by nonthermal fluctuations.

A prototypical example of active rigidity, interpreted as a formation of a pseudowell in the effective energy landscape, can be generated in an overdamped stochastic system and the transition from negative to positive rigidity is linked with time correlations in the additive noise.

Generic Long-Range Interactions Between Passive Bodies in an Active Fluid.

It is shown that, when two or more passive bodies are placed in an active fluid, these currents lead to long-range interactions that lead to rich dynamics of the bodies, illustrated by the spontaneous synchronized rotation of pinned nonchiral bodies and the formation of traveling bound pairs.


We develop a new method for proving hypocoercivity for a large class of linear kinetic equations with only one conservation law. Local mass conservation is assumed at the level of the collision

The force on a boundary in active matter

We present a general theory for determining the force (and torque) exerted on a boundary (or body) in active matter. The theory extends the description of passive Brownian colloids to self-propelled
