Avalanches in the Relaxation Dynamics of Electron Glasses
Martin Goethe, Matteo Palassini
We study the zero-temperature relaxation dynamics of an electron glass model with single-electron hops. We find numerically that in the charge rearrangements (avalanches) triggered…
Parallel kinetic Monte Carlo simulation of Coulomb glasses
Ezequiel E. Ferrero, Alejandro B. Kolton, Matteo Palassini
We develop a parallel rejection algorithm to tackle the problem of low acceptance in Monte Carlo methods, and apply it to the simulation of the hopping conduction in Coulomb glasse…
Phase diagram, correlation gap, and critical properties of the Coulomb glass
Martin Goethe, Matteo Palassini
We investigate the lattice Coulomb glass model in three dimensions via Monte Carlo simulations. No evidence for an equilibrium glass phase is found down to very low temperatures, a…
