Feedback cooling scheme for an optically levitated oscillator with controlled cross-talk
J. M. H. Gosling, A. Pontin, F. Alder +3
Levitated optical mechanical systems have demonstrated excellent force and impulse sensitivity and are currently being developed for the creation of non-classical states of motion…

Strong coupling and dark modes in the motion of a pair of levitated nanoparticles
Antonio Pontin, Quentin Deplano, Andrea Ranfagni +2
We experimentally investigate a system composed of two levitating nanospheres whose motions are indirectly coupled via coherent scattering in a single optical cavity mode. The nano…

Coulomb coupling between two nanospheres trapped in a bichromatic optical tweezer
Quentin Deplano, Antonio Pontin, Andrea Ranfagni +2
Levitated optomechanics is entering the multiparticle regime, paving the way for the use of arrays of strongly coupled massive oscillators to explore complex interacting quantum sy…
