Solving PDEs with Spatial & Time Varying Coefficients: Dirac Wave Function Passes Through EM Wave

A. J. Kalinowski1
1Consultant

The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψn n=1…4. This wave function describes the behavior of fermion type particles. The effect of a ... Read More
