Description
In this presentation I will provide an update on research at the Quantum Technologies and Dark Matter Laboratories at the University of Western Australia to develop new techniques to search for wave-like dark matter candidates and to test fundamental physics using precision low-energy metrology.
In particular we will focus on techniques which utilize low-loss and low-noise electromagnetic oscillators [1,2], that search for signs of axions, scalar dark matter, quantum gravity. And high frequency gravitational waves [3-8]
