Non-decomposable quantum dynamical semigroups and bound entangled states
Fabio Benatti, Roberto Floreanini, Marco Piani
We use open quantum system techniques to construct one-parameter semigroups of positive maps and apply them to study the entanglement properties of a class of 16-dimensional densit…
Entanglement generation in the Unruh effect
F. Benatti, R. Floreanini
The master equation describing the completely positive time evolution of a uniformly accelerated two-level system in weak interaction with a scalar field in the Minkowski vacuum is…
Complete positivity and dissipative factorized dynamics: some comments
F. Benatti, R. Floreanini, M. Piani +1
After reviewing the main properties of time-evolutions of open quantum systems, some considerations about the positivity of factorized Markovian dynamics for bipartite systems are…
Classical Limit of Quantum Dynamical Entropies
F. Benatti, V. Cappellini, M. De Cock +2
Two non-commutative dynamical entropies are studied in connection with the classical limit. For systems with a strongly chaotic classical limit, the Kolmogorov-Sinai invariant is r…
Complete positivity and dissipative factorized dynamics
F. Benatti, R. Floreanini, R. Romano
We show that any Hermiticity and trace preserving continuous semigroup gamma_t in d dimensions is completely positive if and only if the semigroup gamma_t otimes gamma_t is positiv…
Multi-time correlations in relaxing quantum dynamical systems
J. Andries, F. Benatti, M. De Cock +1
In this paper, we consider the long time asymptotics of multi-time correlation functions for quantum dynamical systems that are sufficiently random to relax to a ``reference state'…
