Abstract:

The classical limit problem that appears in some quantum systems when observed using certain spaces of observables is addressed. For conceptual reasons, the problem is divided into two different processes: statistical and localization. By examining the statistical process, it is proven that certain quantum systems evolve from a statistical quantum state to the statistical classical final stationary state. For the localization process, the classical motion of a single system is derived.
