Under certain conditions, two samples of fluid at different initial temperatures present a
counterintuitive behavior known as the Mpemba effect: it is the hotter system that cools …

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 …

Configurational entropy (S conf) is known to be a key thermodynamic factor governing a
glass transition process. However, this significance remains speculative because S conf is …

We evidence a Kovacs-like memory effect in a uniformly driven granular gas. A system of
inelastic hard particles, in the low density limit, can reach a nonequilibrium steady state …

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 …

Understanding the properties of supercooled water is important for developing a
comprehensive theory for liquid water and amorphous ices. Because of rapid crystallization …

Glasses are interesting materials because they allow us to explore the puzzling properties of
out-of-equilibrium systems. One of them is the Kovacs effect in which a glass, brought to an …

We investigate the memory effect in a simple model for glassy relaxation, a trap model with a
Gaussian density of states. In this model, thermal equilibrium is reached at all finite …

The accuracy of a model to describe the horizontal dynamics of a confined quasi-two-
dimensional system of inelastic hard spheres is discussed by comparing its predictions for …

The Kovacs effect is a remarkable feature of the ageing dynamics of glass forming liquids
near the glass transition temperature. It consists in a non-monotonous evolution of the …
