A phase-space study of the quantum Loschmidt Echo in the
... to be well adapted to a semiclassical analysis, in particular with respect to semiclassical estimates of their time evolution. For times not larger than the so-called “Ehrenfest time” C| log ~|, we are able to estimate semiclassically the Loschmidt Echo as a function of t (time), ~ (Planck constant) ...

REDUCED AND EXTENDED WEAK COUPLING LIMIT
... In this article we review various aspects of the weak coupling limit, reduced and, especially, extended, mostly following our papers [DD1, DD2]. We also describe some background material, especially related to completely positive semigroups, quantum Langevin dynamics and the Detailed Balance Conditi ...
