Active systems evade the rules of equilibrium thermodynamics by constantly dissipating
energy at the level of their microscopic components. This energy flux stems from the …

Active matter encompasses systems whose individual constituents dissipate energy to exert
propelling forces on their environment. These systems exhibit dynamical phenomena with …

Within a simple model of attractive active Brownian particles, we predict flocking behavior
and challenge the widespread idea that alignment interactions are necessary to observe this …

We study the thermodynamic properties induced by non-reciprocal interactions between
stochastic degrees of freedom in time-and space-continuous systems. We show that, under …

Active matter systems, from self-propelled colloids to motile bacteria, are characterized by
the conversion of free energy into useful work at the microscopic scale. They involve physics …

Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they
have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized …

In active matter, particles typically experience mediated interactions, which are not
constrained by Newton's third law and are therefore generically non-reciprocal. Non …

Time-reversal symmetry breaking and entropy production are universal features of
nonequilibrium phenomena. Despite its importance in the physics of active and living …

The study of active soft matter has developed into one of the most rapidly growing areas of
physics. Field theories, which can be developed either via phenomenological …

Active constituents burn fuel to sustain individual motion, giving rise to collective effects that
are not seen in systems at thermal equilibrium, such as phase separation with purely …
