Talbot Effect for the Cubic Nonlinear Schrödinger Equation on the Torus

چکیده
We study the evolution of the one dimensional periodic cubic Schrödinger equation (NLS) with bounded variation data. For the linear evolution, it is known that for irrational times the solution is a continuous, nowhere differentiable fractal-like curve. For rational times the solution is a linear combination of finitely many translates of the initial data. Such a dichotomy was fist observed by Talbot in an optical experiment performed in 1836, [20]. In this paper we prove that a similar phenomenon occurs in the case of the NLS equation.

Existence and Uniqueness Theory for the Fractional Schrödinger Equation on the Torus
We study the Cauchy problem for the 1-d periodic fractional Schrödinger equation with cubic nonlinearity. In particular we prove local well-posedness in Sobolev spaces, for solutions evolving from rough initial data. In addition we show the existence of global-in-time infinite energy solutions. Our tools include a new Strichartz estimate on the torus along with ideas that Bourgain developed in ...
متن کاملSobolev stability of plane wave solutions to the cubic nonlinear Schrödinger equation on a torus
It is shown that plane wave solutions to the cubic nonlinear Schrödinger equation on a torus behave orbitally stable under generic perturbations of the initial data that are small in a high-order Sobolev norm, over long times that extend to arbitrary negative powers of the smallness parameter. The perturbation stays small in the same Sobolev norm over such long times. The proof uses a Hamiltoni...
متن کاملSmoothing for the Fractional Schrödinger Equation on the Torus and the Real Line
In this paper we study the cubic fractional nonlinear Schrödinger equation (NLS) on the torus and on the real line. Combining the normal form and the restricted norm methods we prove that the nonlinear part of the solution is smoother than the initial data. Our method applies to both focusing and defocusing nonlinearities. In the case of full dispersion (NLS) and on the torus, the gain is a ful...
متن کاملGrowth of Sobolev norms in the cubic defocusing nonlinear Schrödinger equation
We consider the cubic defocusing nonlinear Schrödinger equation in the two dimensional torus. Fix s > 1. Colliander, Keel, Staffilani, Tao and Takaoka proved in [CKS10] the existence of solutions with s-Sobolev norm growing in time. We establish the existence of solutions with polynomial time estimates. More exactly, there is c > 0 such that for any K ≫ 1 we find a solution u and a time T such ...
متن کاملImproved almost Morawetz estimates for the cubic nonlinear Schrödinger equation
We prove global well-posedness for the cubic, defocusing, nonlinear Schrödinger equation on R2 with data u0 ∈ H s(R2), s > 1/4. We accomplish this by improving the almost Morawetz estimates in [9].
