Orbitally stable standing waves of a mixed dispersion nonlinear Schrödinger equation

Denis Bonheure, Jean-Baptiste Castéras, Ederson Moreira dos Santos +1

We study the mixed dispersion fourth order nonlinear Schrödinger equation \begin{equation*} %\tag{\protect{4NLS}}\label{4nls} i \partial_t ψ-γΔ^2 ψ+βΔψ+|ψ|^{2σ} ψ=0\ \text{in}\ \R…
