Solitons supported by a self-defocusing trap in a fractional-diffraction waveguide
Mateus C. P. dos Santos, Boris A. Malomed, Wesley B. Cardoso
We introduce a model which gives rise to self-trapping of fundamental and higher-order localized states in a one-dimensional nonlinear Schrödinger equation with fractional diffract…

Symmetry Breaking in Bose-Einstein Condensates Confined by a Funnel Potential
Bruno M. Miranda, Mateus C. P. dos Santos, Wesley B. Cardoso
In this work, we consider a Bose-Einstein condensate in the self-focusing regime, confined transversely by a funnel-like potential and axially by a double-well potential formed by…
