Semiclassical rotation dynamics of quantum rigid rotors — •Birthe Papendell1, Benjamin A. Stickler2, and Klaus Hornberger11Faculty of Physics, University of Duisburg Essen, Germany — 2Quantum Optics and Laser Science, Imperial College London, United Kingdom

Recent progress in the optical manipulation [1,2] of levitated aspherical nanoparticles and the prospect of cooling them into their ro-translational ground state [3] open the door for rotational quantum experiments with nanoscale particles [4]. However, calculating the exact rotational quantum dynamics of such objects is numerically intractable due to the high number of involved rotation states. Here, we present semiclassical approximation methods for planar and linear rigid rotors with several thousand occupied angular momentum states revolving in the presence of an external potential.
