Title: Local management of the nonlinearity of Bose-Einstein condensates with pinched potentials
Authors: Ariel Guerreiro
Nuno Azevedo Silva
Issue Date: 2016
Abstract: We present a proposal for the local control of the nonlinearity in quasi-one-dimensional Bose-Einstein condensates induced by a local pinching of the transverse confining potential. We investigate the scattering of bright matter-wave solitons through a pinched potential using numerical simulations of the full three-dimensional Gross-Pitaevskii equation and the corresponding effective one-dimensional model with spatially varying nonlinearity.
