Testing decoherence in interference experiments with macromolecules : the theoretical background

A self-contained quantum description of the measured intensity for interferometry with macromolecules was discussed. The analysis was based on two main ingredients which include the formula for the statistics of particle arrival position and the discription of the dynamics of a test particles filling the medium. The treatment can be simplified by a phenomenological discription which reduce the density matrix of the system evolves autonomously with a Boltzmann-type master equation. It was found that the effect of the environment, including the photon emission due the internal cooling of the thermal produced macromolecules which are summarized by a collision term, added to free dynamics of the system, which takes into account the decoherence.
