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

Rotations of rigid bodies exhibit pronounced quantum phenomena that do not exist for their center-of-mass motion. By levitating nanoparticles in ultra-high vacuum, researchers are developing a promising platform for observing and exploiting these quantum effects in an unexplored mass and size regime [1]. This talk will discuss the prospects of observing orientational quantum revivals [2], quantum tennis racket flips [3], and spin-controlled interference [4] with nanoscale particles. I will review how rotational cooling into the quantum regime can be achieved [5] and how environmental decoherence impacts quantum experiments with nanoscale rotors [6].
