Resonant light-light interaction in slab waveguides: angular filters and spectral hole burning
A. V. Gorbach, V. Fleurov, S. Flach +1
We consider the process of low-power light scattering by optical solitons in a slab waveguide with homogeneous and inhomogeneous refractive index core. We observe resonant reflecti…
Fano resonance in two-dimensional optical waveguide arrays with a bi-modal defect
Rodrigo A. Vicencio, Andrey V. Gorbach, Sergej Flach
We study the two-dimensional extension of the Fano-Anderson model on the basis of a two-dimensional optical waveguide array with a bi-modal defect. We demonstrate numerically the p…
Quantum dynamics of localized excitations in a symmetric trimer molecule
R. A. Pinto, S. Flach
We study the time evolution of localized (local bond) excitations in a symmetric quantum trimer molecule. We relate the dynamical properties of localized excitations such as their…
q-Breathers and the Fermi-Pasta-Ulam Problem
S. Flach, M. V. Ivanchenko, O. I. Kanakov
The Fermi-Pasta-Ulam (FPU) paradox consists of the nonequipartition of energy among normal modes of a weakly anharmonic atomic chain model. In the harmonic limit each normal mode c…
Energy Flow Puzzle of Soliton Ratchets
S. Denisov, S. Flach, A. Gorbach
We study the mechanism of directed energy transport for soliton ratchets. The energy flow appears due to the progressive motion of a soliton (kink) which is an energy carrier. Howe…
