Dynamics of Charged Spin-1/2 Particles in Superposed States Coupled to Electromagnetism in Curved Spacetime within the WKB Approximation
The dynamics of charged spin-1/2 particles in superposed states minimally coupled to electromagnetism in curved spacetime can be described using a Wentzel–Kramers–Brillouin (WKB) approximation of the Dirac equation, which yields equations of motion and spin dynamics for the particles.
