We review the general aspects of the concept of temperature in equilibrium and non-
equilibrium statistical mechanics. Although temperature is an old and well-established …

Recent investigations of the phase diagram of spherical, purely repulsive, active particles
established the existence of a transition from a liquidlike to a solidlike phase analogous to …

Granular materials are ubiquitous in nature and are also employed in many industrial
settings such as those involving chemical processes, pharmaceutical products, mining, and …

The aim of this review is to provide a concise overview of some of the generic approaches
that have been developed to deal with the statistical description of large systems of …

The vibrational dynamics of solids is described by phonons constituting basic collective
excitations in equilibrium crystals. Here, we consider a non-equilibrium active solid, formed …

We derive the hydrodynamics for a system of N active, spherical, underdamped particles,
interacting through conservative forces. At the microscopic level, we represent the evolution …

High-resolution interferometric observations of the circumstellar environments of AGB stars
show a variety of morphologies. Guided by the unusual carbon monoxide line profile of the …

Confined granular fluids, placed in a shallow box that is vibrated vertically, can achieve
homogeneous stationary states due to energy injection mechanisms that take place …

We derive generalized fluctuation–dissipation relations (FDR) holding for a general
stochastic dynamics that includes as subcases both equilibrium models for passive colloids …

The transport coefficients of a granular fluid driven by a stochastic bath with friction are
obtained by solving the inelastic Enskog kinetic equation from the Chapman-Enskog …
