The authors demonstrate a two-dimensional optomechanical crystal cavity which traps a phonon mode within a phononic bandgap while yielding large thermal conductivity to the environment. High quantum cooperativity at millikelvin temperatures is realiz

Using pulsed optical excitation and read-out along with single-phonon-counting techniques, we measure the transient backaction, heating, and damping dynamics of a nanoscale silicon optomechanical crystal cavity mounted in a dilution refrigerator at a

Optomechanical systems offer new opportunities in quantum information processing and quantum sensing. Many solid-state quantum devices operate at millikelvin temperatures -- however, it has proven challenging to operate nanoscale optomechanical devic

The energy damping time in a mechanical resonator is critical to many precision metrology applications, such as timekeeping and force measurements. We present measurements of the phonon lifetime of a microwave-frequency, nanoscale silicon acoustic ca

We present the design and characterization of a quasi-two-dimensional optomechanical crystal cavity. At a refrigerated temperature of 10 mK, an intrinsic mechanical quality factor of 1.2 billion is observed and an effective quantum cooperativity grea

Using an optical probe along with single photon detection we have performed effective phonon counting measurements of the acoustic emission and absorption processes in a nanomechanical resonator. Applying these measurements in a Hanbury Brown and Twi
