Spatial solitons rays in periodic optical lattices
Ramaz Khomeriki, Jerome Leon
The light ray of a spatial soliton in an optical film whose refractive index is smoothly modulated (wavelength much larger than the typical soliton width) in both spatial direction…

Gap soliton dynamics in an optical lattice as a parametrically driven pendulum
Ramaz Khomeriki, Jerome Leon
A long wavelength optical lattice is generated in a two-level medium by low-frequency contrapropagating beams. Then a short wave length gap soliton generated by evanescent boundary…

Delocalization and spreading in a nonlinear Stark ladder
Dmitry O. Krimer, Ramaz Khomeriki, Sergej Flach
We study the evolution of a wave packet in a nonlinear Schrödinger lattice equation subject to a dc bias. In the absence of nonlinearity all normal modes are spatially localized gi…
