Title:  Quantum interference of levitated nanorotors

 16:00 CET, ZOOM 

​

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 review rotational quantum effects and show how they can be observed with levitated nanoparticles. As an example, I will discuss how the quantum rotations of nanodiamonds can be controlled via microwave-driving of embedded spins [2,3].
