Experiments with levitated optomechanics — •Hendrik Ulbricht — Department of Physics and Astronomy, University of Southampton, SO17 1BJ, Southampton, UK

We will report on our experiments with levitated optomechanical systems relevant for both sensing applications and the study of fundamental physics. Such experiments include optical parametric feedback cooling towards the quantum mechanical ground state, generation of squeezed motional states of thermal ensembles, rotation and precession motion, measurement of surface forces and the implementation of real-time Kalman filters to manipulate the motion of trapped nanoparticles in vacuum.
