Two-dimensional gap solitons in elliptic-lattice potentials
Two-dimensional gap solitons elliptic-lattice potentials
2010/4/2
We study two-dimensional (2D) matter-wave gap solitons trapped in an elliptically deformed concentric lattice potential, within the framework of the Gross-Pitaevskii equation (GPE) with self-attractio...
Solitons in combined linear and nonlinear lattice potentials
Solitons nonlinear lattice potentials combined linear
2010/4/1
We study ordinary solitons and gap solitons (GSs) in the effectively one-dimensional Gross-Pitaevskii equation, with a combination of linear and nonlinear lattice potentials. The main points of the an...
