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…

Stable and unstable vortices in multicomponent Bose-Einstein condensates
Juan J. Garcia-Ripoll, Victor M. Perez-Garcia
We study the stability and dynamics of vortices in two-species condensates as prepared in the recent JILA experiment (M. R. Andrews {\em et al.}, Phys. Rev. Lett. 83 (1999) 2498).…
