Dynamics of superconducting microscale rotors — •Fynn Köller, Klaus Hornberger, and Benjamin A. Stickler — University of Duisburg-Essen, Lotharstraße 1, 47048 Duisburg, Germany

The rotation dynamics of magnetizable objects can be affected strongly by spin-rotational coupling since their internal magnetization field contributes to their total angular momentum. Starting from the classical equations of motion, this poster will derive the Hamiltonian of a superconducting rotor of ellipsoidal shape levitated diamagnetically in a magnetostatic quadrupole field. We will discuss how signatures of strong spin-rotational coupling might become observable in upcoming experiments in the field of levitated nanomechanics and discuss the prospects for magnetic-field sensing.
