Probing gravitational interaction between milligram optomechanical oscillators operating in the quantum regime
M. Bonaldi, A. Borrielli, G. Di Giuseppe +12
We present an ongoing optomechanical experiment aimed at detecting gravitational interaction between milligram-scale oscillators, and exploring its interplay with quantum mechanics…
Stationary entanglement of a levitated oscillator with an optical field
Q. Deplano, A. Pontin, F. Marino +1
Stationary entanglement between the motion of macroscopic objects and light is a long-standing goal of quantum optomechanics, with implications for both fundamental tests of quantu…
Roto-translational optomechanics
M. Rademacher, A. Pontin, J. M. H. Gosling +2
Levitated optomechanics, the interaction between light and small levitated objects, is a new macroscopic quantum system that is being used as a testing ground for fundamental physi…
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…
High purity two-dimensional levitated mechanical oscillator
Q. Deplano, A. Pontin, A. Ranfagni +2
In recent years, levitated optomechanics has delivered on the promise of reaching the motional quantum ground state. An important next milestone of the field would be the generatio…
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…
