Abstract
It is shown that Van Hove theory of quantum fields, based on the analy tic properties of the resolvent operator, is capable of describing a k ind of non-equilibrium QED states known as partially dressed states. T his result is obtained by investigating the resolvent description of t he time development of the bare ground state of the two-level atom rad iation Hamiltonian using the Coulomb gauge, the minimal coupling schem e and the electric-dipole approximation.
