We prove that the nonexistence of supersonic finite-energy traveling waves for nonlinear Schrodinger equations with nonzero conditions at infinity is a general phenomenon which holds for a large class of equations. The same is true for sonic traveling waves in two dimensions. In higher dimensions we prove that sonic traveling waves, if they exist, must approach their limit at infinity in a very rigid way. In particular, we infer that there are no sonic traveling waves with finite energy and…

Travelling waves for the nonlinear Schrödinger equation with general nonlinearity in dimension one

It is shown that even though the nonlinearity has the same behaviour as the well-known Gross–PitaevskiiNonlinearity, the qualitative properties of the travelling waves may be extremely different and the numerical strategy based on the variational structure of the equation is proposed.

Minimal Energy for the Traveling Waves of the Landau-Lifshitz Equation

The main result is the existence of a minimal energy for these traveling waves, in dimensions two, three, and four, which relies on a priori estimates related to the theory of harmonic maps and the connection of the Landau--Lifshitz equation with the kernels appearing in the Gross--Pitaevskii equation.
