Nonequilibrium relaxation and scaling properties of the two-dimensional Coulomb glass in the aging regime

TL;DR

This study uses Monte Carlo simulations to analyze the aging dynamics of a two-dimensional Coulomb glass, revealing non-universal scaling behavior dependent on temperature and charge density.

Contribution

It demonstrates that the nonequilibrium relaxation in the Coulomb glass follows a full aging scaling form with non-universal exponents, advancing understanding of disordered correlated systems.

Findings

Aging scaling ansatz accurately describes relaxation dynamics.

Scaling exponents vary with temperature and charge density.

System exhibits non-universal aging behavior.

Abstract

We employ Monte Carlo simulations to investigate the two-time density autocorrelation function for the two-dimensional Coulomb glass. We find that the nonequilibrium relaxation properties of this highly correlated disordered system can be described by a full aging scaling ansatz. The scaling exponents are non-universal, and depend on temperature and charge density.
