Local controllability of a 1-D Schrödinger equation

چکیده
We consider a non relativistic charged particle in a 1-D box of potential. This quantum system is subject to a control, which is a uniform electric field. It is represented by a complex probability amplitude solution of a Schrödinger equation. We prove the local controllability of this nonlinear system around the ground state. Our proof uses the return method, a Nash-Moser implicit function theorem and moment theory. Résumé: On considère une particule non relativiste dans un puits de potentiel en dimension un d’espace. Ce systeme quantique est soumis à un champ électrique uniforme, qui constitue un contrôle. Il est représenté par une densité de probabilité complexe solution d’une équation de Schrödinger. On démontre la contrôlabilité locale de ce système non linéaire au voisinage de l’état fondamental. La preuve utilise la méthode du retour, un théorème de Nash-Moser et la théorie des moments.

Control and Stabilization of the Nonlinear Schrödinger Equation on Rectangles
This paper studies the local exact controllability and the local stabilization of the semilinear Schrödinger equation posed on a product of n intervals (n ≥ 1). Both internal and boundary controls are considered, and the results are given with periodic (resp. Dirichlet or Neumann) boundary conditions. In the case of internal control, we obtain local controllability results which are sharp as fa...
متن کاملGlobal controllability and stabilization for the nonlinear Schrödinger equation on an interval
We prove global internal controllability in large time for the nonlinear Schrödinger equation on a bounded interval with periodic, Dirichlet or Neumann conditions. Our strategy combines stabilization and local controllability near 0. We use Bourgain spaces to prove this result on L 2. We also get a regularity result about the control if the data are assumed smoother.
متن کاملControllability of the 1D Schrödinger equation by the flatness approach
We derive in a straightforward way the exact controllability of the 1-D Schrödinger equation with a Dirichlet boundary control. We use the so-called flatness approach, which consists in parameterizing the solution and the control by the derivatives of a “flat output”. This provides an explicit control input achieving the exact controllability in the energy space. As an application, we derive an...
متن کاملGeneric controllability of the bilinear Schrödinger equation on 1-D domains: the case of measurable potentials
Several sufficient conditions for the controllability of the Schrödinger equation have been proposed in the last few years. In this article we discuss the genericity of these conditions with respect to the variation of the controlled or the uncontrolled potential. In the case where the Schrödinger equation is set on a domain of dimension one, we improve the results in the literature, removing f...
متن کاملLocal exact controllability of the 2D-Schrödinger-Poisson system
In this article, we investigate the exact controllability of the 2DSchrödinger-Poisson system, which couples a Schrödinger equation on a bounded domain of R with a Poisson equation for the electrical potential. The control acts on the system through a Neumann boundary condition on the potential, locally distributed on the boundary of the space domain. We prove several results, with or without n...
