Rotational quantum revivals of nanoscale particles — •Birthe Papendell, Benjamin A. Stickler, and Klaus Hornberger — Fakultät für Physik, Universität Duisburg-Essen

Recent progress in the optical manipulation [1-4] of levitated nanoparticles as well as the prospect of ro-translational ground state cooling [5] open the door for quantum experiments with orientational coherences. We present a scheme for the observation of quantum revivals in the rotation state of a nanoparticle in high vacuum. To assess the feasibility of the setup the rotational quantum dynamics nanometer-sized double-walled carbon nanotubes is studied in presence of environmental decoherence.
