Numerical study of transverse (in-)stability of solitary waves in the cubic-quintic nonlinear Schrödinger equation
Christian Klein, Christof Sparber
We study the nonlinear Schrödinger equation with a competing cubic-quintic power law nonlinearity on the waveguide domain . This model is globa…

Numerical evidence for singularity formation in defocusing fractional NLS in one space dimension
Christian Klein, Christof Sparber
We consider nonlinear dispersive equations of Schrödinger-type involving fractional powers of the Laplacian and a defocusing power-law nonlinearity. We conduct numerica…
