Decoherence and Irreversibility: the role of the reservoir effective Hilbert space size
Adelcio C. Oliveira, A. R. Bosco de Magalhaes
We show that decoherence is determined by the effective Hilbert space size, and demonstrate that a few degrees of freedom system can simulate a "N" degrees of freedom environment i…

Short Time Dynamics of Scalar Products in Hilbert Space
Adélcio C. Oliveira
We use the semiclassical method proposed in \cite{Adelcio2003} to study scalar products such as the overlap, Husimi functions and fidelity decay. Scars of classical periodic orbits…
