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…
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…
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…
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…
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…
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…
Search for ultralight dark matter in the SuperMAG high-fidelity dataset
Matt Friel, Jesper W. Gjerloev, Saarik Kalia +1
Ultralight dark matter, such as kinetically mixed dark-photon dark matter (DPDM) or axionlike-particle dark matter (axion DM), can source an oscillating magnetic-field signal at Ea…
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…
Tunneling away the relic neutrino asymmetry
Saarik Kalia
The Earth acts as a matter potential for relic neutrinos which modifies their index of refraction from vacuum by . It has been argued that the refractive effects from…
Maglev for Dark Matter: Dark-photon and axion dark matter sensing with levitated superconductors
Gerard Higgins, Saarik Kalia, Zhen Liu
Ultraprecise mechanical sensors offer an exciting avenue for testing new physics. While many of these sensors are tailored to detect inertial forces, magnetically levitated (Maglev…
Curl up with a good : Detecting ultralight dark matter with differential magnetometry
Itay M. Bloch, Saarik Kalia
Ultralight dark matter (such as kinetically mixed dark-photon dark matter or axionlike dark matter) can source an oscillating magnetic-field signal at the Earth's surface, which ca…
A Hunt for Magnetic Signatures of Hidden-Photon and Axion Dark Matter in the Wilderness
Ibrahim A. Sulai, Saarik Kalia, Ariel Arza +17
Earth can act as a transducer to convert ultralight bosonic dark matter (axions and hidden photons) into an oscillating magnetic field with a characteristic pattern across its surf…
Earth as a transducer for axion dark-matter detection
Ariel Arza, Michael A. Fedderke, Peter W. Graham +2
We demonstrate that ultralight axion dark matter with a coupling to photons induces an oscillating global terrestrial magnetic field signal in the presence of the background geomag…
Search for dark-photon dark matter in the SuperMAG geomagnetic field dataset
Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball +1
In our recent companion paper [arXiv:2106.00022], we pointed out a novel signature of ultralight kinetically mixed dark-photon dark matter. This signature is a quasi-monochromatic,…
Warming up cold inflation
William DeRocco, Peter W. Graham, Saarik Kalia
The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axi…
Galactic Geology: Probing Time-Varying Dark Matter Signals with Paleo-Detectors
Sebastian Baum, William DeRocco, Thomas D. P. Edwards +1
Paleo-detectors are a proposed experimental technique to search for dark matter by reading out the damage tracks caused by nuclear recoils in small samples of natural minerals. Unl…
Earth as a transducer for dark-photon dark-matter detection
Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball +1
We propose the use of the Earth as a transducer for ultralight dark-matter detection. In particular we point out a novel signal of kinetically mixed dark-photon dark matter: a mono…
Statistics of Peaks in Chi-Squared Fields
Jolyon K. Bloomfield, Stephen H. P. Face, Alan H. Guth +2
Chi-squared random fields arise naturally from the study of fluctuations in field theories with SO(n) symmetry. The extrema of chi-squared fields are of particular physical interes…
Modeling Smooth Backgrounds and Generic Localized Signals with Gaussian Processes
Meghan Frate, Kyle Cranmer, Saarik Kalia +2
We describe a procedure for constructing a model of a smooth data spectrum using Gaussian processes rather than the historical parametric description. This approach considers a ful…
Number Density of Peaks in a Chi-Squared Field
Jolyon K. Bloomfield, Stephen H. P. Face, Alan H. Guth +3
We investigate the statistics of stationary points in the sum of squares of Gaussian random fields, which we call a "chi-squared" field. The behavior of such a field at a point…
Generalizations of the Szemerédi-Trotter Theorem
Saarik Kalia, Micha Sharir, Noam Solomon +1
We generalize the Szemerédi-Trotter incidence theorem, to bound the number of complete \emph{flags} in higher dimensions. Specifically, for each , we are given a…
