Spin Coherent State Path Integral for the Interaction of Two-Level System with Time Dependent Non-Uniform Magnetic Field
Authors/Creators
Description
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.
