Special Soft + Quantum Slam
In the last few years, it has become possible to cool levitated nanoparticles to the ground-state of an optical potential, opening the possibility of performing quantum experiments with solid objects made out of billions of atoms. In this talk, I will outline why understanding and manipulating the rotation of levitated nanoparticles is key to this endeavour. I will introduce research from my group on controlling the motion and rotation of silicon nano-cylinders. and how they can be used for quantum and classical sensing applications. I will also introduce some novel detection and feedback control technology developed in the group, for tracking and controlling multiple levitated objects simultaneously.
