We study a granular gas of viscoelastic particles, i.e, the kinetic energy loss upon collision, characteristic of granular materials, is a function of the particles relative velocities at impact. In order to characterize thermal memory in this system, we study the temperature relaxation curves when the granular gas is subject to sudden thermostat changes (the gas is heated homogeneously by means of a white noise). Results show that the system may display anomalous cooling and heating velocities… Expand

Mpemba-like effect in a molecular binary mixture in contact with a thermal reservoir
The Mpemba effect occurs when two samples at different initial temperatures evolve in such a way that the temperatures cross each other during the relaxation towards equilibrium. In this paper weExpand

Time-dependent homogeneous states of binary granular suspensions
The time evolution of a homogeneous bidisperse granular suspension is studied in the context of the Enskog kinetic equation. The influence of the surrounding viscous gas on the solid particles isExpand
Mpemba effect in molecular gases under nonlinear drag
We look into the Mpemba effect---the initially hotter sample cools sooner---in a molecular gas with nonlinear viscous drag. Specifically, the gas particles interact among them via elastic collisionsExpand


Velocity distribution function and effective restitution coefficient for a granular gas of viscoelastic particles.
A simplified model of an effective constant restitution coefficient ε(eff), which depends on a current granular temperature, is formulated and computed using the kinetic theory and it is concluded that this model can accurately describe granularTemperature. Expand

A Kovacs-like memory effect in a uniformly driven granular gas is evidence and excellent agreement between the analytical predictions and direct Monte Carlo simulations is found. Expand
Homogeneous steady states in a granular fluid driven by a stochastic bath with friction
The homogeneous state of a granular flow of smooth inelastic hard spheres or disks described by the Enskog–Boltzmann kinetic equation is analyzed. The granular gas is fluidized by the presence of aExpand
Memory effects in the relaxation of a confined granular gas.
It is shown that, in the low-density limit, the Kovacs effect can be accurately described by using a simple kinetic theory based on the first Sonine approximation for the one-particle distribution function. Expand

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, the particles areExpand

Mpemba Index and Anomalous Relaxation
The Mpemba effect is a counter-intuitive relaxation phenomenon, in which a system prepared at a hot temperature cools faster than an identical system starting at a cold temperature when both areExpand
A granular material is a collection of a large number of discrete solid particles. Generally, the interstices between the particles are filled with a fluid such as air or water, and thus,Expand
Kovacs-like memory effect in driven granular gases.
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 are also intrinsic to theExpand
