Title: Dark Matter and other BSM searches with SRF cavities at SQMS<br>
<br>
Abstract: [Meeting URL: <a href="https://ubc.zoom.us/j/62433300804?pwd=VWpNd2F4RDFpYlBQekN5U04zVEVCQT09&from=addon">
https://ubc.zoom.us/j/62433300804?pwd=VWpNd2F4RDFpYlBQekN5U04zVEVCQT09&from=addon</a><br>
Meeting ID: 624 3330 0804<br>
Passcode: 076187]<br>
<br>
The Superconducting Quantum Materials and Systems Center, led by Fermi National Accelerator Laboratory, is one of five research centers funded by the U.S. Department of Energy as part of a national initiative to develop and deploy the world's most powerful
quantum computers and sensors. This presentation will focus on SQMS's efforts to apply SRF cavity and superconducting qubit technology to search for fundamental physics.<br>
<br>
This presentation will focus on the SERAPH experiment, a family of superconducting haloscopes being developed by SQMS to search for wavelike dark matter. In this presentation, I will first discuss the principles behind operating a haloscope whose bandwidth
is much narrower than the dark matter halo energy distribution. I will then describe the first SERAPH experiments implementing a 1.3 GHz Niobium cavity with an ultra-high quality factor (Q~1010) that has achieved the best sensitivity and deepest exclusion
to wavelike dark photon dark matter by almost an order of magnitude. Next, I will discuss progress on the next phase of SERAPH, which will search dark photon dark matter using a widely-tunable SRF cavity (4-7 GHz). I will finally describe plans for subsequent
SERAPH experiments to search for dark photons and axions with tunable SRF cavities tolerant to multi-Tesla magnetic fields and quantum sensors that subvert the Standard Quantum Limit.<br>
<br>
I will also describe other experiments under SQMS using SRF cavities, including heterodyne detection of low-mass axion dark, a light-shining-through-wall dark photon search with DarkSRF, and high-frequency gravitational wave searches.<br>
