Controlling a whispering gallery doublet mode avoided frequency crossing: Strong coupling between photon bosonic and spin degrees of freedom
Maxim Goryachev, Warrick G. Farr, Daniel L. Creedon +1
A combination of electron spin interactions in a magnetic field allows us to control the resonance frequencies of a high-Q Whispering Gallery (WG) cavity mode doublet, resulting in…
Giant -factors of Natural Impurities in Synthetic Quartz
Maxim Goryachev, Warrick G. Farr, Michael E. Tobar
We report the observation of -factors of natural paramagnetic impurities in a pure synthetic quartz crystal at milli-Kelvin temperatures. Measurements are made by performing spe…
Ultrasensitive microwave spectroscopy of paramagnetic impurities of sapphire crystals at millikelvin temperatures
Warrick G. Farr, Daniel L. Creedon, Maxim Goryachev +2
Progress in the emerging field of engineered quantum systems requires the development of devices that can act as quantum memories. The realisation of such devices by doping solid s…
Anomalously Strong Nonlinearity of Unswept Quartz Acoustic Cavities at Liquid Helium Temperatures
M. Goryachev, Warrick G. Farr, Eugene N. Ivanov +1
We demonstrate a variety of nonlinear phenomena at extremely low powers in cryogenic acoustic cavities fabricated from quartz material, which have not undergone any electrodiffusio…
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…
Observation of Rayleigh phonon scattering through excitation of extremely high overtones in low-loss cryogenic acoustic cavities for hybrid quantum systems
M. Goryachev, D. L. Creedon, S. Galliou +1
The confinement of high frequency phonons approaching 1 GHz is demonstrated in phonon-trapping acoustic cavities at cryogenic temperatures using a low-coupled network approach. The…
