Localized and periodic exact solutions to the nonlinear Schrodinger equation with spatially modulated parameters: Linear and nonlinear lattices
Juan Belmonte Beitia, Vladimir V. Konotop, Victor M. Perez Garcia +1
Using similarity transformations we construct explicit solutions of the nonlinear Schrodinger equation with linear and nonlinear periodic potentials. We present explicit forms of s…
Defect modes of a Bose-Einstein condensate in an optical lattice with a localized impurity
V. A. Brazhnyi, V. V. Konotop, V. M. Pérez-García
We study defect modes of a Bose-Einstein condensate in an optical lattice with a localized defect within the framework of the one-dimensional Gross-Pitaevskii equation. It is shown…
Construction of exact solutions by spatial traslations in inhomogeneous Nonlinear Schrodinger equations. Applications to Bose-Einstein condensation
Juan J. Garcia-Ripoll, Victor M. Perez-Garcia, Vadym Vekslerchik
In this paper we study a general nonlinear Schrödinger equation with a time dependent harmonic potential. Despite the lack of traslational invariance we find a symmetry trasformati…
Vortex bending and tightly packed vortex lattices in Bose-Einstein condensates
J. J. Garcia-Ripoll, V. M. Perez-Garcia
We study in detail the counterintuitive result that in elongated rotating Bose--Einstein condensates the ground state is composed of one or more vortex lines which bend even in com…
Dipole-Mode Vector Solitons
Juan J. Garcia-Ripoll, Victor M. Perez-Garcia, Elena A. Ostrovskaya +1
We find a new type of optical vector soliton that originates from trapping of a dipole mode by a soliton-induced waveguide. These solitons, which appear as a consequence of the vec…
Nonlocal interactions prevent collapse in negative scattering length Bose-Einstein gases
Victor M. Perez-Garcia, V. V. Konotop, Juan J. Garcia-Ripoll
We study the effect of nonlocality on the collapse properties of a self-focusing Nonlinear Schrödinger system related to Bose-Einstein condensation problems. Using a combination of…
