Levitated Nanophysics Group

Our work on optical control of levitated nanorods has been published in Optica!

Kuhn, Kosloff et al., Optica 4, 356-360 (2017)

I am very excited to announce a new paper we have put online. By driving the motion of a levitated nano-rod, we have created the highest quality rotations ever observed. This has profound implications for force sensing.

Very pleased that our recent work on cavity cooling levitated nanoparticles has been chosen as a highlight in Nature Photonics!

Cooling Dynamics

We were very happy to visit the Zemánek Group at ISI Brno, to discuss future collaborations, and for James to present the latest results from Vienna.

Very pleased to announce that our work “Nonlinear Dynamics and Strong Cavity Cooling of Levitated Nanoparticles” has been published in Physical Review Letters as an Editor’s Suggestion.

This work smashes the record for cooling nanoparticles with an optical cavity, reaching millikelvin temperatures. We also uncovered some interesting non-linear dynamics along the way, which have important applications in future quantum physics experiments.

Our nanofabrication collaborators, the Patolsky group at Tel Aviv University, have published a paper outlining their amazing method for producing silicon nanoparticles; we like to call it the “nanosalami” technique!

Nanodicing Single Crystalline Silicon Nanowire Arrays

The Hornberger Group at the University of Duisburg-Essen, the long-time collaborators of the Vienna Quantum Nanophysics group, have published two back-to-back papers inspired by our research.

Spatial decoherence: Phys. Rev. A 94, 033828
Rotational cavity cooling: Phys. Rev. A 94, 033818

Very pleased to announce that we have a paper covering the trapping and rotational control of silicon nanorods online. You can find it on arxiv:

Full Rotational Control of Levitated Silicon Nanorods

I was pleased to talk at the huge SPIE conference in San Diego this year, it was great to get some new (non-quantum!) perspectives on optical trapping.

I delivered a tutorial on Optomechanics to the SFB meeting in Innsbruck. Oh man did it rain!
