Abstract

In 1983, Wigner outlined &modified Schröinger-von- Neumann equation of motion for macroobjects, to describe their typical coupling to the environment. This equation has become a principal model of environmental decoherence which is believed responsible for the emergence of classicality in macroscopic quantum systems. Typically, this happens gradually and asymptotically after a certain characteristic decoherence time. For the Wigner function, however, one can prove that it evolves perfectly into a classical (non-negative) phase-space distribution after a finite time of decoherence.
