Spin Coherent State Path Integral For The Interaction Of Two-Level System With Time Dependent Non-Uniform Magnetic Field
Rima Rekik, Mekki Aouachria
We study the movement of a two-level atom in interaction with time dependent nonuniform magnetic filed using the path integral formalism. The propagator is first written in the standard form by replacing the spin by a unit vector aligned along the polar and azimuthal directions. Then it is determined exactly using perturbation methods. Thus the Rabi formula of the system are deduced.
