Speaker: M. Toros (University of Southampton)

We give a pedagogical introduction to the detection of anisotropic nanoparticles in levitated optomechanics. We obtain the full rotational and translational dynamics, as well as, the measured photo-current in a dyne detection [1].  We discuss the recent experimental observation of light torque-induced precession and nutation of a trapped particle [2].
