Measuring High-Order Phonon Correlations in an Optomechanical Resonator

Yogesh S. S. Patil, Jiaxin Yu, Sean Frazier +5

We use single photon detectors to probe the motional state of a superfluid ${}^4$He resonator of mass $\sim 1$ ng. The arrival times of Stokes and anti-Stokes photons (scattered by th…
