Geometric phase for open quantum systems and stochastic unravellings
A. Bassi, E. Ippoliti
We analyze the geometric phase for an open quantum system when computed by resorting to a stochastic unravelling of the reduced density matrix (quantum jump approach or stochastic…
Identical particles and entanglement
GianCarlo Ghirardi, Luca Marinatto
We review two general criteria for deciding whether a pure bipartite quantum state describing a system of two identical particles is entangled or not. The first one considers the p…
Nonlocality without inequalities
GianCarlo Ghirardi, Luca Marinatto
We prove that every conceivable hidden variable model reproducing the quantum mechanical predictions of almost any entangled state must necessarily violate Bell's locality conditio…
Mechanical similarity as a generalization of scale symmetry
E. Gozzi, D. Mauro
In this paper we study the symmetry known as mechanical similarity (LMS) and present for any monomial potential. We analyze it in the framework of the Koopman-von Neumann formulati…
Controlling Entanglement Generation in External Quantum Fields
F. Benatti, R. Floreanini
Two, non-interacting two-level atoms immersed in a common bath can become mutually entangled when evolving with a Markovian, completely positive dynamics. For an environment made o…
Quantum dynamical entropies for discrete classical systems: a comparison
Valerio Cappellini
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…
