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

@inproceedings{Patron2021StrongNR, 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}, year={2021} }

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…

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.
