Improved Dark Photon Sensitivity from the Dark SRF Experiment
Saarik Kalia, Zhen Liu, Bianca Giaccone +15
We report the refined dark-photon exclusion bound from Dark SRF's pathfinder run. Our new result is driven by improved theoretical modeling of frequency instability in high-quality…

Modeling frequency instability in high-quality resonant experiments
Hao-Ran Cui, Saarik Kalia, Zhen Liu
Modern resonant sensing tools can achieve increasingly high quality factors, which correspond to extremely narrow linewidths. In such systems, time-variation of the resonator's nat…

Ultralight dark matter detection with levitated ferromagnets
Saarik Kalia, Dmitry Budker, Derek F. Jackson Kimball +7
Levitated ferromagnets act as ultraprecise magnetometers, which can exhibit high quality factors due to their excellent isolation from the environment. These instruments can be uti…
