Temperature coefficients of crystalline-quartz elastic constants over the cryogenic range [4 K, 15 K]
Jérémy Bon, Serge Galliou, Roger Bourquin
This paper brings out results of a measurement campaign aiming to determine the temperature coefficients of synthetic quartz elastic constants at liquid helium temperature. The met…
A new method of probing mechanical losses of coatings at cryogenic temperatures
Serge Galliou, Samuel Deléglise, Maxim Goryachev +14
A new method of probing mechanical losses and comparing the corresponding deposition processes of metallic and dielectric coatings in 1-100 MHz frequency range and cryogenic temper…
Measurements of Elastic Properties of Langatate at Liquid Helium Temperatures for design of ultra low loss mechanical systems
Maxim Goryachev, Philippe Abbe, Bernard Dulmet +2
We present full characterisation of acoustic wave devices based on the fully synthetic crystalline material at the liquid helium temperature range { required for the design of ultr…
Extremely Low Loss Phonon-Trapping Cryogenic Acoustic Cavities for Future Physical Experiments
S. Galliou, M. Goryachev, R. Bourquin +3
Low loss Bulk Acoustic Wave devices are considered from the point of view of the solid state approach as phonon-confining cavities. We demonstrate effective design of such acoustic…
Extremely Low-Loss Acoustic Phonons in a Quartz Bulk Acoustic Wave Resonator at Millikelvin Temperature
Maxim Goryachev, Daniel L. Creedon, Eugene N. Ivanov +3
Low-loss, high frequency acoustic resonators cooled to millikelvin temperatures are a topic of great interest for application to hybrid quantum systems. When cooled to 20 mK, we sh…
