Orbital stability in the cubic defocusing NLS equation: I. Cnoidal periodic waves
Periodic waves of the one-dimensional cubic defocusing NLS equation are considered. Using tools from integrability theory, these waves have been shown in [4] to be linearly stable and the Floquet–Bloch spectrum of the linearized operator has been explicitly computed. We combine here the first four conserved quantities of the NLS equation to give a direct proof that cnoidal periodic waves are or...
متن کاملThe Semiclassical Limit of the Defocusing NLS Hierarchy
We establish the semiclassical limit of the one-dimensional defocusing cubic nonlinear Schrödinger (NLS) equation. Complete integrability is exploited to obtain a global characterization of the weak limits of the entire NLS hierarchy of conserved densities as the field evolves from reflectionless initial data under all the associated commuting flows. Consequently, this also establishes the zero...
متن کامل20 07 Invariant Measures for the Defocusing Nls
We prove the existence and the invariance of a Gibbs measure associated to the defocusing sub-quintic Nonlinear Schrödinger equations on the disc of the plane R 2. We also prove an estimate giving some intuition to what may happen in 3 dimensions. Résumé. On démontre l'existence et l'invariance d'une mesure de Gibbs par le flot de l'´ equation de Schrödinger non linéaire posée sur le disque du ...
متن کاملA lower bound for the power of periodic solutions of the defocusing Discrete Nonlinear Schrödinger equation
We derive lower bounds on the power of breather solutions ψn(t) = e −iΩtφn, Ω > 0 of a Discrete Nonlinear Schrödinger Equation with cubic or higher order nonlinearity and site-dependent anharmonic parameter, supplemented with Dirichlet boundary conditions. For the case of a defocusing DNLS, one of the lower bounds depends not only on the dimension of the lattice, the lattice spacing, and the fr...
متن کاملStability of exact solutions of the defocusing nonlinear Schrödinger equation with periodic potential in two dimensions
The cubic nonlinear Schrödinger equation with repulsive nonlinearity and elliptic function potential in two-dimensions models a repulsive dilute gas Bose–Einstein condensate in a lattice potential. A family of exact stationary solutions is presented and its stability is examined using analytical and numerical methods. All stable trivial-phase solutions are off-set from the zero level. Our resul...
