Abstract

By means of a quantum optical description the connection between decoherence, dephasing and depolarization is shown. The transition from a quantum state to a mixture is caused by the interaction of the neutron with fluctuating and dissipative forces in matter or magnetic fields. An analytical description of this effect provides the basis for phase sensitive investigations of condensed matter with polarized neutrons. Analogies between the coherence function and the beam polarization will be discussed.
