Description
I present a simple very general random matrix model for
quantum spins interacting with a large external system. It
allows to study and illustrate in a simple framework various
quantum-to-classical phenomena: the decoherence dynamics,
the emergence of the classical phase space for a quantum
system, quantum and classical diffusion in phase space, the
conditions for non-Markovian and Markovian behaviors.
