Partially incoherent gap solitons in Bose-Einstein condensates
I. M. Merhasin, Boris A. Malomed, Y. B. Band
We construct families of incoherent matter-wave solitons in a repulsive degenerate Bose gas trapped in an optical lattice (OL), i.e., gap solitons, and investigate their stability…
Gap solitons in Bragg gratings with a harmonic superlattice
K. Yagasaki, I. M. Merhasin, B. A. Malomed +2
Solitons are studied in a model of a fiber Bragg grating (BG) whose local reflectivity is subjected to periodic modulation. The superlattice opens an infinite number of new bandgap…
Alternate solitons: Nonlinearly-managed one- and two-dimensional solitons in optical lattices
Arthur Gubeskys, Boris A. Malomed, Ilya M. Merhasin
We consider a model of Bose-Einstein condensates which combines a stationary optical lattice (OL) and periodic change of the sign of the scattering length (SL) due to the Feshbach-…
Two-component gap solitons in two- and one-dimensional Bose-Einstein condensates
A. Gubeskys, B. A. Malomed, I. M. Merhasin
We introduce 2D and 1D models of a binary Bose-Einstein condensate in a periodic potential, with repulsive interactions. We chiefly consider the most fundamental case of the inter-…
Gap solitons in a model of a hollow optical fiber
I. M. Merhasin, Boris A. Malomed
We introduce a models for two coupled waves propagating in a hollow-core fiber: a linear dispersionless core mode, and a dispersive nonlinear quasi-surface one. The linear coupling…
