Abstract

The Maxwell-Dirac equations are the equations for electronic matter, the &#34;classical&#34; theory underlying QED. In this article we examine the stationary Maxwell-Dirac equations under weak regularity and decay assumptions. We prove that: There are no embedded eigenvalues in the essential spectrum, -m≤ E≤ m. If |E|< m then the Dirac field components (and their derivatives) decay exponentially at spatial infinity. If E|=m then the system is &#34;asymptotically&#34; static and decays exponentially if the total charge is non-zero.
