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

Understand

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.
