Contribution

It demonstrates the presence of memory effects in classical and quantum mean-field disordered models using the Kovacs protocol, linking theoretical models to experimental phenomena.

Findings

Classical and quantum p-spin models exhibit Kovacs memory effects.

Memory effects in these models resemble those in super-cooled polymer melts.

Potential for applying similar protocols to quantum glassy systems.

Abstract

We apply the Kovacs experimental protocol to classical and quantum p-spin models. We show that these models have memory effects as those observed experimentally in super-cooled polymer melts. We discuss our results in connection to other classical models that capture memory effects. We propose that a similar protocol applied to quantum glassy systems might be useful to understand their dynamics.
