Together with our collaboration partners from the Technical University of Vienna we have realised open-access silicon microcavities. Their low mode-volume has allowed us to detect 300 nm silica nanoparticles via their strong coupling to the cavity field. This work has been published as an Editor’s pick in Applied Physics Letters:

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:

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.
The Erwin Schrödinger Center for Quantum Science & Technology (Austrian Academy of Science) has granted me the project Rotational Quantum Optomechanics (ROTOQUOP) to study the rotational cooling of silicon nanorods. I will be working on ROTOQUOP for 12 months starting from February 1st.
Our work on controlling the rotational motion of a tiny silicon rod, optically levitated in vacuum, was published in Optica: Full rotational control of levitated silicon nanorods, Optica 4, 356-360.
