Hysteretic depinning of a particle in a periodic potential: Phase diagram and criticality
Víctor H. Purrello, José L. Iguain, Vivien Lecomte +1
We consider a massive particle driven with a constant force in a periodic potential and subjected to a dissipative friction. As a function of the drive and damping, the phase diagr…
Transient magnetic domain wall AC dynamics by means of MOKE microscopy
Pablo Domenichini, Cintia Quinteros, Mara Granada +6
The domain wall response under constant external magnetic fields reveals a complex behavior where sample disorder plays a key role. Furthermore, the response to alternating magneti…
First passage time for superstatistical Fokker-Planck models
Adrián A. Budini, Manuel O. Cáceres
The first passage time (FPT) problem is studied for superstatistical models assuming that the mesoscopic system dynamics is described by a Fokker-Planck equation. We show that all…
The Prandtl-Tomlinson model of friction with stochastic driving
E. A. Jagla
We consider the classical Prandtl-Tomlinson model of a particle moving on a corrugated potential, pulled by a spring. In the usual situation in which pulling acts at constant veloc…
Aftershock production rate of driven viscoelastic interfaces
E. A. Jagla
We study analytically and by numerical simulations the statistics of the aftershocks generated after large avalanches in models of interface depinning that include viscoelastic rel…
Symmetry for the duration of entropy-consuming intervals
Reinaldo García-García, Daniel Domínguez
We introduce the violation fraction as the cumulative fraction of time that a mesoscopic system spends consuming entropy at a single trajectory in phase space. We show t…
