Abstract

The theory of decoherence in a matter wave Talbot-Lau interferometer was analyzed. It was observed that the loss of interference contrast could be calculated using a Wigner description of the stationary beam. It was also observed that the formulation includes the decohering coupling to the environment and the coherent interaction with the grating walls. The realistic microscopic descriptions of the experimentally relevant interactions were developed and showed that the treatment was equivalent to solving the corresponding master equation in paraxial approximation.
