Abstract

We propose a new algorithm for solving the semiclassical timedependent Schrödinger equation The algorithm is based on semiclassical wavepackets The focus of the analysis is only on the time discretization convergence is proved to be quadratic in the time step and linear in the semiclassical parameter varepsilon
