QuaSeRT Mid Term Meeting – general informations

The Mid Term Meeting of the QuaSeRT project will be held June 4-5 in Florence. The conference venue is Villa Il Gioiello (https://www.msn.unifi.it/ls-15-villa-galileo.html), the last dwelling of Galileo Galilei.

The first day of the meeting (starting at 11:00) is open access. People interested in participating can contact us by May 15th (please use the contact form of the site). No registration fee is required. 

The second day of the meeting will be dedicated to the presentation of preliminary results of the project and to the discussion among the researchers of the QuaSeRT collaboration.

Levitated cavity optomechanics in high vacuum

The paper “Levitated cavity optomechanics in high vacuum” is available on arXiv:1902.06605.

We report dispersive coupling of an optically trapped silica nanoparticle (143 nm diameter) to the field of a driven Fabry-Perot cavity in high vacuum (4.3×10−6 mbar). We demonstrate nanometer-level control in positioning the particle with respect to the intensity distribution of the cavity field, which allows access to linear, quadratic and tertiary optomechanical interactions in the resolved sideband regime. We determine all relevant coupling rates of the system, i.e. mechanical and optical losses as well as optomechanical interaction, and obtain a quantum cooperativity of CQ=0.01. Based on the presented performance the regime of strong cooperativity (CQ>1) is clearly within reach by further decreasing the mode volume of the cavity.
