Dense active systems are widespread in nature, examples range from bacterial colonies to
biological tissues. Dense clusters of active particles can be obtained by increasing the …

In an equilibrium thermal environment, random elastic collisions between background
particles and a tracer establish the picture of Brownian motion fulfilling the celebrated …

Chiral active matter is enjoying a rapid increase of interest, spurred by the rich variety of
asymmetries that can be attained in, eg, the shape or self-propulsion mechanism of active …

We use numerical simulations to study the dynamics of dense assemblies of self-propelled
particles in the limit of extremely large, but finite, persistence times. In this limit, the system …

Inertial effects affecting both the translational and rotational dynamics are inherent to a
broad range of active systems at the macroscopic scale. Thus, there is a pivotal need for …

We study the collective vibrational excitations of crystals under out-of-equilibrium steady
conditions that give rise to entropy production. Their excitation spectrum comprises …

Understanding actual transport mechanisms of self-propelled particles (SPPs) in complex
elastic gels—such as in the cell cytoplasm, in in vitro networks of chromatin or of F-actin …

Dense or glassy active matter, as a result of its remarkable resemblance to passive glass-
forming materials, is enjoying increasing scientific interest. To better grasp the subtle effect …

We investigate the interplay between chirality and confinement induced by the presence of
an external potential. For potentials having radial symmetry, the circular character of the …

Recent years have seen a rapid increase of interest in dense active materials, which, in the
disordered state, share striking similarities with the conventional passive glass-forming …
