Optically levitated rotors: potential control and optimal measurement — •Martin Frimmer — Photonics Laboratory, ETH Zürich, Switzerland

Optically levitated nanoparticles have attracted significant attention recently and especially their rotational degrees of freedom offer exciting opportunities for sensing and quantum physics. The quantum control recently achieved for the center-of-mass motion of a levitated scatterer is to be extended to the orientational degrees of freedom of anisotropic scatterers. In this talk, we address the problem of optimally detecting the librational degrees of freedom of an anisotropic dielectric scatterer. Furthermore, we discuss a method to tune the conservative potential governing the librational degrees of freedom in an optical focus while keeping the center-of-mass motion trapped.
