Precision Frequency Techniques to Search for Dark Matter and New Physics with Photonic, Phononic and Atomic Oscillators

In these proceedings we summarise a collection of recent experimental results in which high precision photonic, phononic and atomic oscillators are used to probe for new physics, such as searching for wave-like dark matter, performing Lorentz invariance tests, looking for high frequency gravitational waves and more. We focus our discussions on summarising our most recent work on a new method for constraining scalar dark matter using a photonic microwave cavity, phononic quartz mechanical resonator and atomic hydrogen transition in conjunction, while also briefly summarising various other experimental results.
