There is only one time
Caterina Foti, Alessandro Coppo, Giulio Barni +2
We draw a picture of physical systems that allows us to recognize what is this thing called "time" by requiring consistency not only with our notion of time but also with the way t…
From a quantum theory to a classical one
Alessandro Coppo, Alessandro Cuccoli, Caterina Foti +1
We present and discuss a formal approach for describing the quantum to classical crossover based on the group-theoretic construction of generalized coherent states. The method was…
A dynamical model for Positive-Operator Valued Measures
A. De Pasquale, C. Foti, A. Cuccoli +2
We tackle the dynamical description of the quantum measurement process, by explicitly addressing the interaction between the system under investigation with the measurement apparat…
Whenever a quantum environment emerges as a classical system, it behaves like a measuring apparatus
Caterina Foti, Teiko Heinosaari, Sabrina Maniscalco +1
We study the dynamics of a quantum system with an environment made of elementary quantum components. We aim at answering the following questions: can the evolution of $…
