Dark Matter-Wave Solitons in Optical Lattices
Pearl J. Y. Louis, Elena A. Ostrovskaya, Yuri S. Kivshar
We analyze the Floquet-Bloch matter-wave spectrum of Bose-Einstein condensates loaded into single-periodic optical lattices and double-periodic superlattices. In the framework of t…
Second-harmonic generation in vortex-induced waveguides
José R. Salgueiro, Andreas Carlsson, Elena Ostrovskaya +1
We study the second-harmonic generation and localization of light in a reconfigurable waveguide induced by an optical vortex soliton in a defocusing Kerr medium. We show that the v…
Localization of Two-Component Bose-Einstein Condensates in Optical Lattices
Elena A. Ostrovskaya, Yuri S. Kivshar
We reveal underlying principles of nonlinear localization of a two-component Bose-Einstein condensate loaded into a one-dimensional optical lattice. Our theory shows that spin-depe…
Observation of discrete vortex solitons in optically-induced photonic lattices
Dragomir N. Neshev, Tristram J. Alexander, Elena A. Ostrovskaya +4
We report on the frst experimental observation of discrete vortex solitons in two-dimensional optically-induced photonic lattices. We demonstrate strong stabilization of an optical…
Band-gap solitons in nonlinear optically-induced lattices
Anton S. Desyatnikov, Elena A. Ostrovskaya, Yuri S. Kivshar +1
We introduce novel optical solitons that consist of a periodic and a spatially localized components coupled nonlinearly via cross-phase modulation. The spatially localized optical…
Matter-wave gap solitons in atomic bandgap structures
Elena A. Ostrovskaya, Yuri S. Kivshar
We demonstrate that a Bose-Einstein condensate in an optical lattice forms a reconfigurable matter-wave structure with a band-gap spectrum, which resembles a nonlinear photonic cry…
