Semiclassical Asymptotics for the Maxwell - Dirac System
arXiv:math-ph/0305009 · doi:10.1063/1.1604455
Abstract
We study the coupled system of Maxwell and Dirac equations from a semiclassical point of view. A rigorous nonlinear WKB-analysis, locally in time, for solutions of (critical) order $O(\sqrtε)$ is performed, where the small semiclassical parameter $ε$ denotes the microscopic/macroscopic scale ratio.
