The nondissipative damping of the Rabi oscillations as a "whichpath" information
Abstract
Rabi oscillations may be viewed as an interference phenomenon due to a coherent superposition of different quantum paths, as in Young's twoslit experiment. The inclusion of the atomic external variables causes a nondissipative damping of the Rabi oscillations. More generally, the atomic translational dynamics induces damping in the correlation functions which describe nonclassical behaviors of the field and internal atomic variables, leading to the separability of these two subsystems. We discuss on the possibility of interpreting this intrinsic decoherence as a "whichway" information effect and we apply to this case a quantitative analysis of the complementarity relation as introduced by Englert (Phys. Rev. Lett. 77 (1996) 2154).
