Path integral method for inelastic scattering-a modified Pechukas approach
Journal of Physics G: Nuclear Physics 10:1 (1984) 81-89
Abstract:
A new derivation of correction terms to the primitive semiclassical amplitude for multiple inelastic scattering is presented. It is shown that a modification of the path integral method used by Pechukas yields correction terms in agreement with the results obtained in a recent paper by Sukumar and Brink.Solution of the Heisenberg equations for an atom interacting with radiation

Abstract:
It is shown that the nonlinear equation of motion for the energy operator of a few-level atom interacting with a single mode radiation field can be solved explicitly.Some soluble models for periodic decay and revival

Abstract:
The authors present three analytically tractable models for a two-level atom interacting with a coherent or thermal radiation field and study the behaviour of the atomic excitation energy for various initial conditions.Quantization through wave-packet coupling between the classically allowed and forbidden regions
Physics Letters B 134:6 (1984) 383-386
Abstract:
The projectors P ̂ and Q ̂ are associated to the classically forbidden and allowed regions, respectively. A finite rank algorithm provides the propagator (E - Q ̂ H ̂ Q ̂)-1. A generalized connection between a Bohr-Sommerfeld-like rule and the Bloch-Horowitz theory is found. © 1984.Path integral methods for inelastic scattering
