Phase space diffusion and low temperature aging

TL;DR

This paper investigates how systems with randomly energized configurations evolve over time at low temperatures, revealing aging phenomena driven by Glauber dynamics.

Contribution

It introduces a model demonstrating aging at low temperatures through phase space diffusion using Glauber dynamics.

Findings

Aging occurs even at very low temperatures.

Systems explore lower energy configurations over time.

Glauber dynamics facilitate phase space diffusion.

Abstract

We study the dynamical evolution of a system with a phase space consisting of configurations with random energies. The dynamics we use is of Glauber type. It allows for some dynamical evolution ang aging even at very low temperatures, through the search of configurations with lower energies.
