Active matter physics is about systems in which energy is dissipated at some local level to
produce work. This is a generic situation, particularly in the living world but not only. What is …

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

We study the statistical properties of active Ornstein-Uhlenbeck particles (AOUPs). In this
simplest of models, the Gaussian white noise of overdamped Brownian colloids is replaced …

Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

We establish the complete phase diagram of self-propelled hard disks in two spatial
dimensions from the analysis of the equation of state and the statistics of local order …

Pair interactions between active particles need not follow Newton's third law. In this work, we
propose a continuum model of pattern formation due to nonreciprocal interaction between …

These lecture notes are designed to provide a brief introduction into the phenomenology of
active matter and to present some of the analytical tools used to rationalize the emergent …

Studies of active matter, from molecular assemblies to animal groups, have revealed two
broad classes of behaviour: a tendency to align yields orientational order and collective …

Active-matter systems operate far from equilibrium because of the continuous energy
injection at the scale of constituent particles. At larger scales, described by coarse-grained …

It is known that purely repulsive self-propelled colloids can undergo bulk liquid-vapor phase
separation. In experiments and large-scale simulations, however, more complex steady …
