dc-biased stationary transport in the absence of dissipation
S. Denisov, S. Flach, P. Hanggi
We obtain stationary transport in a Hamiltonian system with ac driving in the presence of a dc bias. A particle in a periodic potential under the influence of a time-periodic field…
Compactlike discrete breathers in systems with nonlinear and nonlocal dispersive terms
A. V. Gorbach, S. Flach
Discrete breathers with purely anharmonic short-range interaction potentials localize super-exponentially becoming compact-like. We analyze their spatial localization properties an…
Classical and quantum radiation of perturbed discrete breathers
S. Flach, V. Fleurov, A. V. Gorbach
We show that the linearized phase space flow around a discrete breather solution is not capable of generating persistent energy flow away from the breather even in the case of inst…
Discrete breathers in Fermi-Pasta-Ulam lattices
S. Flach, A. Gorbach
The Fermi-Pasta-Ulam (FPU) paradox was observed fifty years ago. The surprising finding was a localization of energy in the reciprocal q-space of a model with discrete translationa…
Resonant light scattering by optical solitons
S. Flach, V. Fleurov, A. V. Gorbach +1
We consider the process of light scattering by optical solitons in a planar waveguide with homogeneous and inhomogeneous refractive index core. We observe resonant reflection (Fano…
