Structural relaxation and aging scaling in the Coulomb and Bose glass models

Abstract

Abstract. We employ Monte Carlo simulations to study the relaxation properties of the two-dimensional Coulomb glass in disordered semiconductors and the three-dimensional Bose glass in type-II superconductors in the presence of extended linear defects. We investigate the effects of adding non-zero random on-site energies from different distributions on the properties of the correlation-induced Coulomb gap in the density of states (DOS) and on the non-equilibrium aging kinetics highlighted by the density autocorrelation functions. We also probe the sensitivity of the system's equilibrium and non-equilibrium relaxation properties to instantaneous changes in the density of charge carriers in the Coulomb glass or flux lines in the Bose glass.

Aging phenomena in the two-dimensional complex Ginzburg-Landau equation

“…Aging phenomena have been established to exist in a broad variety of physical systems [4], which range, e.g., from simple Ising ferromagnetics [6][7][8], isotropic antiferromagnets [9], disordered magnets [10], spin glasses [11], disordered electronic Coulomb glass systems [12][13][14], magnetic flux lines in type-II superconductors [15][16][17][18][19][20][21][22], disordered semiconductors [23,24], and skyrmion topological defects [25,26] to driven lattice gases [27,28], population dynamics models [29], and driven-dissipative Bose-Einstein condensation [30]. We remark that most of the above investigations utilized Monte Carlo or molecular dynamics computer simulations.…”
