General aspects of the Fluctuation–Dissipation Relation (FDR), and Response Theory are
considered. After analyzing the conceptual and historical relevance of fluctuations in …

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 …

The contact dynamics (CD) method is presented as a discrete element method for the
simulation of nonsmooth granular dynamics at the scale of particle rearrangements where …

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

In the past thirty years, the area of spin glasses has experienced rapid growth, including the
development of solvable models for glassy systems. Yet these developments have only …

Active matter may sometimes behave almost indistinguishably from equilibrium matter. This
is particularly evident for some particle-based models and active field-theories close to a …

While memory effects have been reported for dense enough disordered systems such as
glasses, we show here by a combination of analytical and simulation techniques that they …

We are used to measuring temperature with a thermometer, and we know from everyday life
that different types of thermometers measure the same temperature. This experience can be …

This brief offers a concise presentation of granular fluids from the point of view of non-
equilibrium statistical physics. The emphasis is on fluctuations, which can be large in …

Abstract A Generalized Langevin Equation with exponential memory is proposed for the
dynamics of a massive intruder in a dense granular fluid. The model reproduces numerical …
