Non-equilibrium memory effects: granular fluids and beyond
A Patrón, B. Sánchez-Rey, C. A. Plata +1
In this perspective paper, we look into memory effects in out-of-equilibrium systems. To be concrete, we exemplify memory effects with the paradigmatic case of granular fluids, alt…
Non-equilibrium attractor for non-linear stochastic dynamics
A. Patrón, B. Sánchez-Rey, E. Trizac +1
We study the dynamical behaviour of mesoscopic systems in contact with a thermal bath, described either via a non-linear Langevin equation at the trajectory level -- or the corresp…
Regular and chaotic transport of discrete solitons in asymmetric potentials
J. Cuevas, B. Sánchez-Rey, M. Salerno
Ratchet dynamics of topological solitons of the forced and damped discrete double sine-Gordon system are studied. Directed transport occurring both in regular and in chaotic region…
Interaction of moving discrete breathers with interstitial defects
J. Cuevas, B. Sanchez-Rey, J. C. Eilbeck +1
In this paper, interstitial migration generated by scattering with a mobile breather is investigated numerically in a Frenkel-Kontorova one-dimensional lattice. Consistent with exp…
Approximated profiles for discrete solitons in DNLS lattices
J Cuevas, G James, P G Kevrekidis +2
We study four different approximations for finding the profile of discrete solitons in the one-dimensional Discrete Nonlinear Schrödinger (DNLS) Equation. Three of them are discret…
Comment on "Soliton ratchets induced by excitation of internal modes"
Niurka R. Quintero, Bernardo Sánchez-Rey, Jesús Casado-Pascual
Very recently Willis et al. [Phys. Rev. E {\bf 69}, 056612 (2004)] have used a collective variable theory to explain the appearance of a nonzero energy current in an ac driven, dam…
Hysteresis in vibrated granular media
A. Prados, J. Javier Brey, B. Sanchez-Rey
Some general dynamical properties of models for compaction of granular media based on master equations are analyzed. In particular, a one-dimensional lattice model with short-range…
Simple model with facilitated dynamics for granular compaction
J. Javier Brey, A. Prados, B. Sanchez-Rey
A simple lattice model is used to study compaction in granular media. As in real experiments, we consider a series of taps separated by large enough waiting times. The relaxation o…
