Talk on "Surface interactions and tunable couplings of a levitated nanosphere"

by George Winstone, University of Southampton, UK

Recent experimental results in measuring the dispersion forces generated between a charged levitated nanosphere and a silicon surface are reviewed. The outlook for investigation of casimir polder forces with a levitated nanoparticle are discussed, as well as near term planned experiments to utilise a nanoparticle as a levitated analogue to an AFM system to perform 2D surface scans. Furthermore, we discuss controlling the couplings between the motional degrees of freedom of the levitated nanoparticle for antiresonant effects and energy transfer between the degrees of freedom.
