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…
Nonlinear Localized Excitations and the Dynamics of H-Bonds in DNA
S. Flach, C. R. Willis
We analyze typical models which intend to describe (parts of) the dynamics of H-Bonds in DNA. We show that these models generically allow for nonlinear localized excitatons (NLEs)…
