Earth as a transducer for ultralight bosonic dark-matter detection
Saarik Kalia, Ibrahim A. Sulai
Ultralight bosonic dark matter (UBDM) that couples to electromagnetism can generate an oscillating magnetic-field signal at the Earth's surface. This is referred to as the ``Earth…
Dynamically generated tilt of isocurvature fluctuations
Saarik Kalia
Light scalar fields acquire isocurvature fluctuations during inflation. While these fluctuations could lead to interesting observable signatures at small scales, they are strongly…
Global detector network to search for high-frequency gravitational waves (GravNet): conceptual design
Dorian Amaral, Diego Blas, Yuliia Borysenkova +30
We propose GravNet (Global detector network to search for high-frequency gravitational waves), a novel experimental scheme enabling the search for gravitational waves in the MHz to…
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…
Stamps of state on structure: Probing the state of ultralight dark matter via its density fluctuations
Saarik Kalia
Dark matter (DM) candidates with very small masses, and correspondingly large number densities, have gained significant interest in recent years. These DM candidates are typically…
