Studying complex relaxation behaviors is of critical importance for understanding the nature
of glasses. Here we report a Kovacs-like memory effect in glasses, manifested by non …

As opposed to the common monotonic relaxation process of glasses, the Kovacs memory
effect describes an isothermal annealing experiment, in which the enthalpy and volume of a …

Despite extensive research, the fundamental physical mechanisms underlying the Mpemba
effect, a phenomenon where a substance cools faster after initially being heated, remain …

The understanding of the dynamics of nonequilibrium cooling and heating processes at the
nanoscale is still an open problem. These processes can follow surprising relaxation paths …

We study a granular gas of viscoelastic particles (kinetic energy loss upon collision is a
function of the particles' relative velocities at impact) subject to a stochastic thermostat. We …

In this perspective paper, we look into memory effects in out-of-equilibrium systems. To be
concrete, we exemplify memory effects with the paradigmatic case of granular fluids …

Control of cooling and heating processes is essential in many industrial and biological
processes. In fact, the time evolution of an observable quantity may differ according to the …

Athermal systems across a large range of length scales, ranging from foams and granular
bead packings to crumpled metallic sheets, exhibit slow stress relaxation when compressed …

The structural origin of the memory effect is still elusive in glassy materials. In this letter, the
memory effect in a series of metallic glasses (MGs) is observed by two step annealing using …

A challenging frontier in modern statistical physics is concerned with systems with a small
number of degrees of freedom, far from the thermodynamic limit. Beyond the general interest …
