The nonequilibrium physics of many-body quantum systems harbors various unconventional
phenomena. In this Letter, we experimentally investigate one of the most puzzling of these …

The highly complicated nature of far from equilibrium systems can lead to a complete
breakdown of the physical intuition developed in equilibrium. A famous example of this is the …

Entanglement asymmetry, which serves as a diagnostic tool for symmetry breaking and a
proxy for thermalization, has recently been proposed and studied in the context of symmetry …

The Mpemba effect is a counterintuitive phenomena in which a hot system reaches a cold
temperature faster than a colder system, under otherwise identical conditions. Here, we …

The quantum Mpemba effect is the counterintuitive nonequilibrium phenomenon wherein
the dynamic restoration of a broken symmetry occurs more rapidly when the initial state …

An ancient and counterintuitive phenomenon known as the Mpemba effect (water can cool
faster when initially heated up) showcases the critical role of initial conditions in relaxation …

Entanglement asymmetry is a quantity recently introduced to measure how much a
symmetry is broken in a part of an extended quantum system. It has been employed to …

When a system's parameter is abruptly changed, a relaxation toward the new equilibrium of
the system follows. We show that a crossing between the second and third eigenvalues of …

The Mpemba effect describes the situation in which a hot system cools faster than an
identical copy that is initiated at a colder temperature. In many of the experimental …

The entanglement asymmetry is an observable independent tool to investigate the
relaxation of quantum many-body systems through the restoration of an initially broken …
