Quantum rotations of levitated nanoparticles — •Benjamin A. Stickler — Faculty of Physics, University of Duisburg-Essen, Germany

The non-linearity and anharmonicity of rigid body rotations gives rise to pronounced quantum interference effects with no analogue in the body's centre-of-mass motion [1]. This talk will briefly review two such effects, orientational quantum revivals [2] and the quantum tennis racket effect [3], and discuss how elliptic coherent scattering cooling [4] opens the door to rotational quantum experiments with nanoscale particles and rotational tests of collapse models.
