Local Exact Controllability of a One-Dimensional Nonlinear Schrödinger Equation

Abstract : We consider a one-dimensional nonlinear Schrödinger equation, modeling a Bose--Einstein condensate in an infinite square-well potential (box). This is a nonlinear control system in which the state is the wave function of the Bose--Einstein condensate and the control is the length of the box. We prove that local exact controllability around the ground state (associated with a fixed length of the box) holds generically with respect to the chemical potential $\mu $, i.e., up to an at most countable set of $\mu $-values. The proof relies on the linearization principle and the inverse mapping theorem, as well as ideas from analytic perturbation theory. Read More: http://epubs.siam.org/doi/10.1137/140951618
