Theory of decoherence due to scattering events and Levy processes / B. Vacchini. - In: PHYSICAL REVIEW LETTERS. - ISSN 0031-9007. - 95:23(2005), pp. 230402.230402-1-230402.230402-4. [10.1103/PhysRevLett.95.230402]
Abstract:
A general connection between the characteristic function of a Levy process and loss of coherence of the statistical operator describing the center of mass degrees of freedom of a quantum system interacting through momentum transfer events with an environment is established. The relationship with microphysical models and recent experiments is considered, focusing on the recently observed transition between a dynamics described by a compound Poisson process and a Gaussian process.
