Linear response in the uniformly heated granular gas
B. Sánchez-Rey, A. Prados
We analyse the linear response properties of the uniformly heated granular gas. The intensity of the stochastic driving fixes the value of the granular temperature in the non-equil…

Classical and quantum nonlinear localized excitations in discrete systems
F. R. Romero, J. F. R. Archilla, F. Palmero +4
Discrete breathers, or intrinsic localized modes, are spatially localized, time--periodic, nonlinear excitations that can exist and propagate in systems of coupled dynamical units.…

Analytical approach to soliton ratchets in asymmetric potentials
Niurka R. Quintero, Bernardo Sánchez-Rey, Mario Salerno
We use soliton perturbation theory and collective coordinate ansatz to investigate the mechanism of soliton ratchets in a driven and damped asymmetric double sine-Gordon equation.…
