We will report on recent progress in our levitated optomechanics experiment. We exploit a coherent scattering approach which has allowed a significant acceleration of the field in recent years. In this setting, a tweezer levitated nanoparticle interacts with the optical field of a Fabry-Perot cavity which is driven solely by light resonantly scattered by the particle itself. The interaction with the cavity field leads to a cross-coupling of the motional degrees of freedom (DoF) in the tweezer polarization plane so that the two DoFs are mixed. We will experimentally show that away from the cavity node, where most experiments have been working, there is a “sweet spot” where competing processes prevent the cavity from mixing these DoFs. While currently in the weak coupling regime, this effect could prevent the formation of bright/dark modes when the strong coupling is reached.
