Non-equilibrium relaxation of an elastic string in a random potential
Alejandro Kolton, Alberto Rosso, Thierry Giamarchi
We study the non--equilibrium motion of an elastic string in a two dimensional pinning landscape using Langevin dynamics simulations. The relaxation of a line, initially flat, is c…
Creep motion of an elastic string in a random potential
Alejandro B. Kolton, Alberto Rosso, Thierry Giamarchi
We study the creep motion of an elastic string in a two dimensional pinning landscape by Langevin dynamics simulations. We find that the Velocity-Force characteristics are well des…
Heterogeneous dynamics of the three dimensional Coulomb glass out of equilibrium
Alejandro B. Kolton, D. R. Grempel, Daniel Dominguez
The non-equilibrium relaxational properties of a three dimensional Coulomb glass model are investigated by kinetic Monte Carlo simulations. Our results suggest a transition from st…
Transverse phase-locking in fully frustrated Josephson junction arrays: a new type of fractional giant steps
Veronica Marconi, Alejandro Kolton, Daniel Dominguez +1
We study, analytically and numerically, phase locking of driven vortex lattices in fully-frustrated Josephson junction arrays at zero temperature. We consider the case when an ac c…
Mode-locking in driven vortex lattices with transverse ac-drive and random pinning
Alejandro B. Kolton, Daniel Dominguez, Niels Gronbech-Jensen
We find mode-locking steps in simulated current-voltage characteristics of driven vortex lattices with {\it random} pinning when an applied ac-current is {\it perpendicular} to the…
Phase-locking of driven vortex lattices with transverse ac-force and periodic pinning
Charles Reichhardt, Alejandro B. Kolton, Daniel Dominguez +1
For a vortex lattice moving in a periodic array we show analytically and numerically that a new type of phase locking occurs in the presence of a longitudinal dc driving force and…
