A Novel Architecture for room temperature microwave optomechanical experiments
Sumit Kumar, Sebastian Spence, Simon Perrett +5
We have developed a novel architecture for room temperature microwave cavity optomechanics, which is based on the coupling of a 3D microwave reentrant cavity to a compliant membran…
Ultra-Low Dissipation Superfluid Micromechanical Resonator
Fabien Souris, Xavier Rojas, Paul H. Kim +1
Micro and nanomechanical resonators with ultra-low dissipation have great potential as useful quantum resources. The superfluid micromechanical resonators presented here possess se…
The giant plasticity of a quantum crystal
Ariel Haziot, Xavier Rojas, Andrew D. Fefferman +2
When submitted to large stresses at high temperature, usual crystals may irreversibly deform. This phenomenon is known as plasticity and it is due to the motion of crystal defects…
He Crystal Quality and Rotational Response in a Transparent Torsional Oscillator
A. D. Fefferman, X. Rojas, A. Haziot +3
We have studied natural purity He single crystals and polycrystals between 10 and 600 mK using a torsional oscillator with a 2 cm rigid cell made of sapphire with a smo…
