In particular, it is shown that such a time can be computed from the poles of the resolvent or of the initial conditions in the complex extension of the Hamiltonian's spectrum. Several decoherence times are estimated: $10^{-13}-$ $10^{-15}s$ for microscopic systems, and $10^{-37}-10^{-39}s$ for macroscopic bodies. For the particular case of a thermal bath, our results agree with those obtained by the einselection (environment-induced decoherence) approach.", "revisions": [ { "version": "v1", "updated": "2005-02-14T19:40:22.000Z" } ], "analyses": { "keywords": [ "decoherence time", "self-induced decoherence", "results agree", "general method", "thermal bath" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
