Focus of the first edition of this book was quantum dynamics in connection with correlations
as carriers of information and entropy as a measure of information. In the same spirit, this …

We study the high-energy limit for eigenfunctions of the Laplacian, on a compact negatively
curved manifold. We review the recent result of Anantharaman–Nonnenmacher (Ann. Inst …

We analyze a model quantum dynamical system subjected to periodic interaction with an
environment, which can describe quantum measurements. Under the condition of strong …

We investigate quantum dynamical systems defined on a finite-dimensional Hilbert space
and subjected to an interaction with an environment. The rate of decoherence of initially …

We study the presence of a logarithmic time scale in discrete approximations of sawtooth
maps on the 2-torus. The techniques used are suggested by quantum mechanical …

We introduce the notion of relaxation time for noisy quantum maps on the 2 d-dimensional
torus–generalization of previously studied dissipation time. We show that the relaxation time …

We analyze the behaviour of two quantum dynamical entropies in connection with the
classical limit. Using strongly chaotic classical dynamical systems as models (Arnold Cat …

We analyze the behavior of quantum dynamical entropies production from sequences of
quantum approximants approaching their (chaotic) classical limit. The model of the …

On a family of classical dynamical systems on the 2-torus, we perform a discretization
procedure similar to the anti-Wick quantization. Such a discretization is performed by using a …

We discuss some recent results concerning the decoherence in controlled quantum open
systems within the mathematical setting corresponding to motion reversal experiments (the …
