Precision oscillator technology with application to testing fundamental physics, detecting high frequency gravitational waves, and quantum measurement

This paper summarises research programs at The University of Western Australia to develop precision oscillator technology based on cryogenic sapphire whispering gallery mode resonators and cryogenic quartz bulk acoustic wave oscillators. Research programs include precision tests of fundamental physics, experiments to detect high frequency gravitational waves and cosmic dark sector particles, as well as quantum measurement, and in particular to measure large mass harmonic oscillators at the ground state.
