A semi-Lagrangian time splitting method for the Schrödinger equation with vector potentials∗
In this paper, we present a time splitting scheme for the Schrödinger equation in the presence of electromagnetic eld in the semi-classical regime, where the wave function propagates O(ε) oscillations in space and time. With the operator splitting technique, the time evolution of the Schrödinger equation is divided into three parts: the kinetic step, the convection step and the potential step. ...
متن کاملOn Fourier time-splitting methods for nonlinear Schrödinger equations in the semi-classical limit II. Analytic regularity
We consider the time discretization based on Lie-Trotter splitting, for the nonlinear Schrödinger equation, in the semi-classical limit, with initial data under the form of WKB states. We show that both the exact and the numerical solutions keep a WKB structure, on a time interval independent of the Planck constant. We prove error estimates, which show that the quadratic observables can be comp...
متن کاملSINGULAR LAGRANGIAN MANIFOLDS and SEMI-CLASSICAL ANALYSIS
Lagrangian submanifolds of symplectic manifolds are very central objects in classical mechanics and microlocal analysis. These manifolds are frequently singular (integrable systems, bifurcations, reduction). There has been a lot of works on singular Lagrangian manifolds initiated by Arnold, Givental and others. The goal of our paper is to extend the classical and semi-classical normal forms of ...
متن کاملA semi-discrete scheme for the stochastic nonlinear Schrödinger equation
We study the convergence of a semi-discretized version of a numerical scheme for a stochastic nonlinear Schrödinger equation. The nonlinear term is a power law and the noise is multiplicative with a Stratonovich product. Our scheme is implicit in the deterministic part of the equation as is usual for conservative equations. We also use an implicit discretization of the noise which is better sui...
متن کاملGaussian Beam Methods for the Schrödinger Equation in the Semi-classical Regime: Lagrangian and Eulerian Formulations
The solution to the Schrödinger equation is highly oscillatory when the rescaled Planck constant ε is small in the semiclassical regime. A direct numerical simulation requires the mesh size to be O(ε). The Gaussian beam method is an efficient way to solve the high frequency wave equations asymptotically, outperforming the geometric optics method in that the Gaussian beam method is accurate even...
