| contents | This paper deals with the existence of travelling wave solutions for a general one-dimensional nonlinear Schrödinger equation. We construct these solutions by minimizing the energy under the constraint of fixed momentum. We also prove that the family of minimizers is stable. Our method is based on recent articles about the orbital stability for the classical and non-local Gross-Pitaevskii equations [3, 10]. It relies on a concentration-compactness theorem, which provides some compactness for the minimizing sequences and thus the convergence (up to a subsequence) towards a travelling wave solution. |
