Discrete Breathers in Two-Dimensional Anisotropic Nonlinear Schrodinger lattices
J. Gomez-Gardenes, L. M. Floria, A. R. Bishop
We study the structure and stability of discrete breathers (both pinned and mobile) in two-dimensional nonlinear anisotropic Schrodinger lattices. Starting from a set of identical…
Discrete Solitons in the Salerno Model with competing nonlinearities
J. Gomez-Gardenes, B. A. Malomed, L. M. Floria +1
We consider a lattice equation (Salerno model) combining onsite self-focusing and intersite self-defocusing cubic terms, which may describe a Bose-Einstein condensate of dipolar at…
Statics and Dynamics of an Inhomogeneously-Nonlinear Lattice
Debra L. Machacek, Elizabeth A. Foreman, Q. E. Hoq +4
We introduce an inhomogeneously-nonlinear Schr{ö}dinger lattice, featuring a defocusing segment, a focusing segment and a transitional interface between the two. We illustrate that…
