|Title:||Universal decay of the classical Loschmidt echo of neutrally stable mixing dynamics||Authors:||Casati, G.
|Issue Date:||25-Mar-2005||Citation:||Casati, G., Prosen, T., Lan, J., Li, B. (2005-03-25). Universal decay of the classical Loschmidt echo of neutrally stable mixing dynamics. Physical Review Letters 94 (11) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevLett.94.114101||Abstract:||We provide analytical and numerical evidence that the classical mixing systems, which lack exponential sensitivity on initial conditions, exhibit universal decay of the Loschmidt echo which turns out to be a function of a single scaled time variable δ2/5t, where δ is the strength of perturbation. The role of dynamical instability and entropy production is discussed. © 2005 The American Physical Society.||Source Title:||Physical Review Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/98524||ISSN:||00319007||DOI:||10.1103/PhysRevLett.94.114101|
