Semiclassical Limit of the Dirac Equatio
✍ Herbert Spohn πŸ“‚ Article πŸ“… 2000 πŸ› Elsevier Science 🌐 English βš– 126 KB

We study the Dirac equation with slowly varying external potentials. Using matrix-valued Wigner functions we prove that the electron follows with high precision the classical orbit and that the spin precesses according to the BMT equation with gyromagnetic ratio g=2. 2000

A Projector Path Integral for the Dirac

We construct a new kind of path integral for the Dirac equation propagator, intended as an extension to 3 space dimensions of the Feynman ``checkerboard'' propagator. One form of this path integral is a ``projector path'' summation, out of which one can reconstruct standard 3D space and chirality. O
