Low-energy searches for new physics (Dark Matter talk for the AIP)
Despite all recent successes in experimental physics including detection of gravitational waves and observation of the Higgs boson, our understanding of the Universe is incomplete with quite a few open questions. One particular question is composition of Dark Matter which is the central topic of the research of the ARC Centre of Excellence for Dark Matter Particle Physics. Although its existence has been witnessed by a number of astrophysical observations, its direct detection is still a major challenge for experimental physics despite an ever-growing number of various approaches and attempts.

In this talk, I will overview different dark matter detection experiments which are under development at the University of Western Australia: ORGAN (targeting high mass axions), UPLOAD/DOWNLOAD (a novel frequency metrology experiment targeting axions), axion wind, scalar dark matter searches as well as R&D towards future cryogenic low mass WIMP detectors.

All these experiments employ low noise precision measurement techniques and could benefit from quantum metrology. Also, I will describe some related low energy experimental searches including High Frequency Gravitational Waves, Lorentz Invariance tests in the matter sector and tests of the generalized uncertainty principle.

Overall, low energy experiments backed up by precision and quantum metrology open new frontiers in experimental searches for new physics resulting in new technologies.
