Treatment Of Spin-1/2 Particle In Interaction With A Time-Dependent Magnetic Field By The Fermionic Coherent-State Path-Integral Formalism
Mekki Aouachria
We consider a spin-1/2 particle interacting with a time-dependent magnetic field using path integral formalism. The propagator is first of all written in the standard form replacing the spin by two fermionic oscillators via the Schwinger model. The propagator is then exactly determined, thanks to a simple transformation, and the transition probability is deduced.
