Decoherence and the rate of entropy production in chaotic quantum systems | | D Monteoliva
; J P Paz

16 Oct 2000 | | Journal: | Phys Rev Lett, 85 (16), 3373-6 | | Abstract: | We show that for an open quantum system which is classically chaotic (a quartic double well with harmonic driving coupled to a sea of harmonic oscillators) the rate of entropy production has, as a function of time, two relevant regimes: For short times it is proportional to the diffusion coefficient (fixed by the system-environment coupling strength). For longer times (but before equilibration) there is a regime where the entropy production rate is fixed by the Lyapunov exponent. The nature of the transition time between both regimes is investigated. | | Source: | PubMed, pmid11030899 | | Other source: | [GID 348134] quant-ph/0007052 | | Services: | Forum | Review | Favorites | |
