Strong non-exponential relaxation and memory effects in a fluid with non-linear drag

  title={Strong non-exponential relaxation and memory effects in a fluid with non-linear drag},
  author={Antonio Patr'on and B. S'anchez-Rey and Antonio Prados},
We analyse the dynamical evolution of a fluid with non-linear drag, for which binary collisions are elastic, described at the kinetic level by the Enskog-Fokker-Planck equation. This model system, rooted in the theory of non-linear Brownian motion, displays a really complex behaviour when quenched to low temperatures. Its glassy response is controlled by a long-lived non-equilibrium state, independent of the degree of non-linearity and also of the Brownian-Brownian collisions rate. The latter…

Mpemba-like effect protocol for granular gases of inelastic and rough hard disks

We study the conditions under which a Mpemba-like effect emerges in granular gases of inelastic and rough hard disks driven by a class of thermostats characterized by the splitting of the noise



The diffusion coefficient of nonlinear Brownian motion

Nonlinear Brownian motion (BM) refers to cases where the damping constant and possibly also the noise intensity in the Langevin equation depend on the velocity of the particle. Such velocity

Nonlinear Brownian motion

The theory of Brownian motion as described by nonlinear Langevin equations and the corresponding Fokker–Planck equations is discussed. The general problems of the theory of nonlinear Brownian motion

The Kovacs effect: a master equation analysis

The Kovacs or crossover effect is one of the peculiar behaviours exhibited by glasses and other complex, slowly relaxing systems. Roughly it consists of the non-monotonic relaxation to its

Computer simulation of uniformly heated granular fluids

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 are

It is shown that the evolution of the energy following the Kovacs protocol can approximately be expressed as a difference of two monotonously decaying functions and thus the existence of a so-called Kovacs hump whenever these functions are not single exponentials is shown.

Velocity distributions in homogeneous granular fluids: the free and the heated case

Abstract Non-Gaussian properties (cumulants, high energy tails) of the single particle velocity distribution for homogeneous granular fluids of inelastic hard spheres or disks are studied, based on

Universal reference state in a driven homogeneous granular gas.

We study the dynamics of a homogeneous granular gas heated by a stochastic thermostat, in the low density limit. It is found that, before reaching the stationary regime, the system quickly "forgets"

Nonequilibrium Phase Transition to Anomalous Diffusion and Transport in a Basic Model of Nonlinear Brownian Motion.

It is shown that superdiffusion and supertransport emerge as a nonequilibrium critical phenomenon when such a Brownian motion is driven out of thermal equilibrium by a constant force.

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 collisions
