Decoherence Versus the Idealization of Microsystems as Correlation Carriers Between Macrosystems
Ludovico Lanz, Bassano Vacchini
It is argued that the appropriate framework to describe a microsystem as a correlation carrier between a source and a detector is non-equilibrium statistical mechanics for the comp…

Time scales in quantum mechanics by a scattering map
L. Lanz, B. Vacchini
Inside quantum mechanics the problem of decoherence for an isolated, finite system is linked to a coarse-grained description of its dynamics.

Subdynamics through Time Scales and Scattering Maps in Quantum Field Theory
L. Lanz, O. Melsheimer, B. Vacchini
It is argued that the dynamics of an isolated system, due to the concrete procedure by which it is separated from the environment, has a non-Hamiltonian contribution. By a unified…
