Abstract: 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 three such effects, orientational quantum revivals [2], the quantum tennis racket effect [3], and spin-controlled rigid-body rotations [4], and discuss how elliptic coherent scattering cooling [5] opens the door to rotational quantum experiments with nanoscale particles and rotational tests of collapse models.
