Macrorealistic extensions of relativistic quantum theory — •Silas Bischoff and Klaus Hornberger — Fakultät für Physik, Universität Duisburg-Essen

Modifications of non-relativistic quantum mechanics, such as the well known GRW and CSL models [1], are already well understood. In contrast to purely interpretative approaches to quantum foundational problems, macrorealistic extensions yield quantitative predictions that allow for experimental falsification. However, the reconciliation of macrorealism with special relativity is laden with conceptual difficulties hitherto unresolved. We aim to understand and formalize the properties a macrorealistic modification of relativistic QFT is required to exhibit. To that end we critically analyse specific proposals [3-4].
