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 …

Minimal models of active Brownian colloids consisting of self-propelled spherical particles
with purely repulsive interactions have recently been identified as excellent quantitative …

We have measured the spectrum of velocity fluctuations in a granular system confined to a
vertical plane and driven into a homogeneous, steady state by strong vertical vibration. The …

" Granular Gases" are diluted many-particle systems in which the mean free path of the
particles is much larger than the typical particle size, and where particle collisions occur …

Recently, it has been discovered that systems of active Brownian particles (APB) at high
density organise their velocities into coherent domains showing large spatial structures in …

Abstract Direct Monte Carlo simulations of the Enskog-Boltzmann equation for a spatially
uniform system of smooth inelastic spheres are performed. In order to reach a steady state …

We measure time-averaged velocity, density, and temperature fields for steady granular flow
past a wedge. We find the flow to be supersonic with a speed of granular pressure …

We consider the problem of determining the granular temperatures of the components of a
homogeneous binary heated mixture of inelastic hard spheres, in the framework of Enskog …

Brownian dynamics algorithms integrate Langevin equations numerically and allow to probe
long time scales in simulations. A common requirement for such algorithms is that …
