"Spectral properties and classical decays in quantum open systems"
I. García-Mata and M. Saraceno
Phys. Rev. E 69(5) (2004) 056211/1-14
We study the relationship between the spectral properties of diffusive open quantum maps and the classical spectrum of Ruelle-Pollicott resonances. The leading resonances determine the asymptotic time regime for several quantities of interest -the linear entropy, the Loschmidt echo, and the correlations of the initial state. A numerical method that allows an efficient calculation of the leading spectrum is developed using a truncated basis adapted to the dynamics.
