| contents | Levitation in vacuum has evolved into a versatile technique which has already benefited diverse scientific directions, from force sensing and thermodynamics to material science and chemistry. It also holds great promises of advancing the study of quantum mechanics in the unexplored macroscopic regime. While most current levitation platforms are complex and bulky, miniaturization is sought to gain robustness and facilitate their integration into confined settings, such as cryostats or portable devices. Integration on chip is also anticipated to enhance the control over the particle motion through a more precise engineering of optical and electric fields. As a substantial milestone towards this goal, we present here levitation and motion control in high vacuum of a silica nanoparticle at the surface of a hybrid optical-electrostatic chip. By combining fiber-based optical trapping and sensitive position detection with cold damping through planar electrodes, we cool the particle motion to a few hundred phonons. Our results pave the way to the next generation of integrated levitation platforms combining integrated photonics and nanophotonics with engineered electric potentials, towards complex state preparation and read out. |
