On the probabilistic nature of quantum mechanics and the notion of closed systems
Jérémy Faupin, Jürg Fröhlich, Baptiste Schubnel
The notion of "closed systems" in Quantum Mechanics is discussed. For this purpose, we study two models of a quantum-mechanical system spatially far separated from the "rest of…

Semi-Classical Dynamics in Quantum Spin Systems
J. Froehlich, A. Knowles, E. Lenzmann
We consider two limiting regimes, the large-spin and the mean-field limit, for the dynamical evolution of quantum spin systems. We prove that, in these limits, the time evolution o…
