Towards a Lorentz-invariant quantum master equation — •Marduk Bolanos and Klaus Hornberger — Fakultät für Physik, Universität Duisburg-Essen

There is an ongoing effort to test the predictions of quantum theory in systems involving a large number of particles. The experiments performed in the last decade have motivated several measures of the macroscopic character of the systems under study. The empirical measure in [1] is based on a minimal modification to the von Neumann equation, that is invariant under Galilean transformations and induces the quantum-classical transition.

In this project we aim to develop an extension of the method presented in [1], that allows us to analyze on empirical grounds the macroscopic character of photonic experiments described by a Lorentz-invariant theory. As a starting point, in this work we develop a classical master equation with the required invariance property. This result will provide a useful reference when we consider the quantum-classical transition in a relativistic setting.
