Orientational localization in the CSL model — •Björn Schrinski, Benjamin A. Stickler, and Klaus Hornberger — Fakultät für Physik, Universität Duisburg-Essen

Recent experimental progress in the control of anisotropic levitated nano-particles [1-3] holds the promise of accessing the orientational degrees of freedom in the quantum regime and thus testing macrorealistic modifications of quantum mechanics. Here, we discuss how the model of continuous spontaneous localization (CSL) [4] affects the orientational coherence of a nano-particle. In particular, we determine the resulting spatio-orientational localization rates and examine how the angular momentum diffusion might help to improve on existing CSL tests.
