We have realised ultra-stable rotations of a silicon nanorod by locking its motion to an electronic clock. This work has been published in Nature Communications:
S. Kuhn, B. A. Stickler, A. Kosloff, F. Patolsky, K. Hornberger, M. Arndt, J. Millen, Optically driven ultra-stable nanomechanical rotor, Nat. Commun. 8, 1670 (2017)
Our findings have also been picked up by several news-outlets, e.g. by the Austrian newspaper Der Standard: “Physiker konstruieren hochpräzise Uhr mit schwebenden Nano-Zeigern” and phys.org: Nano-watch has steady hands.
