  "abstract": "We explore the stability of far-from-equilibrium metastable states of a three-dimensional Coulomb glass at zero temperature by studying charge avalanches triggered by a slowly varying external electric field. Surprisingly, we identify a sharply defined dynamical (\"depinning\") phase transition from stationary to nonstationary charge displacement at a critical value of the external electric field. Using particle-conserving dynamics, scale-free system-spanning avalanches are observed only at the critical field. We show that the qualitative features of this depinning transition are completely different for an equivalent short-range model, highlighting the key importance of long-range interactions for nonequilibrium dynamics of Coulomb glasses.",

      "abstract": "We explore the stability of far-from-equilibrium metastable states of a three-dimensional Coulomb glass at zero temperature by studying avalanches triggered by an external electric field. Using particle-conserving dynamics, scale-free system-spanning avalanches are only observed when the electric field is equal to or larger than a given depinning electric field. By comparing our results on the Coulomb glass with an equivalent short-range model where no scale-free avalanches are found, we illustrate the importance of the interplay between long-range interactions and disorder.",
