Treatment of a Damped Two-level Atom in an Electromagnetic Wave by the Path Integral Formalism
Mekki Aouachria, L. Chétouani
The applications of the path integral formalism have widely increased since a large class of potentials have been resolved [1]. However, it is quite rare to find an explicit calculation for interactions that include spin [2]. As is commonly known, spin is a fundamental physical notion for the comprehension of atomic propertics. Recently, the behavior of a damped two-level atom with an electromagnetic wave of circular polarization has been studied using the Schrodinger equation approach [3]. The same problem has been considered without damping [4]. The purpose of this article is to deal with this same problem using the path integral formalism. The two-level atom with a mass m and an angular frequency ! has a dipole moment D. The dynamics of the atom in interaction with a wave is described by the following Hamiltonian:
