Convergence to SPDE of the Schrodinger equation with large, random potential
Abstract
We study the asymptotic behavior of solutions to the Schr{\"o}dinger equation with large-amplitude, highly oscillatory, random potential. In dimension , where is the order of the leading operator in the Schr\"odinger equation, we construct the heterogeneous solution by using a Duhamel expansion and prove that it converges in distribution, as the correlation length goes to 0, to the solution of a stochastic differential equation, whose solution is represented as a sum of iterated Stratonovich integral, over the space . The uniqueness of the limiting solution in a dense space of is shown by verifying the property of conservation of mass for the Schr\"odinger equation. In dimension , the solution to the Schr{\"o}dinger equation is shown to converge in to a deterministic Schr{\"o}dinger solution in \cite{ZB-12}.
