First Search for Ultraheavy Dark Matter Using a Magnetically Levitated Particle
Dennis G. Uitenbroek, Dorian W. P. Amaral, Juehang Qin +4
We present the first search for ultraheavy dark matter using a magnetically levitated particle. The POLONAISE experiment uses a milligram-scale ferromagnet levitated in a supercond…
Towards the Direct Detection of Composite Ultraheavy Dark Matter in Quantum Sensor Arrays
Dorian W. P. Amaral, Erqian Cai, Andrew J. Long +2
Quantum sensor arrays have recently been proposed as a promising platform for the direct detection of ultraheavy dark matter, which is typically assumed to behave as a point-like p…
Magnetic Levitation as a New Probe of Non-Newtonian Gravity
Dorian W. P. Amaral, Tim M. Fuchs, Hendrik Ulbricht +1
We present MORRIS (Magnetic Oscillatory Resonator for Rare-Interaction Studies) and propose the first tabletop search for non-Newtonian gravity due to a Yukawa-like fifth force usi…
FlowVAT: Normalizing Flow Variational Inference with Affine-Invariant Tempering
Juehang Qin, Shixiao Liang, Christopher Tunnell
Multi-modal and high-dimensional posteriors present significant challenges for variational inference, causing mode-seeking behavior and collapse despite the theoretical expressiven…
Mechanical Sensors for Ultraheavy Dark Matter Searches via Long-range Forces
Juehang Qin, Dorian W. P. Amaral, Sunil A. Bhave +10
Dark matter candidates with masses around the Planck-scale are theoretically well-motivated, and it has been suggested that it might be possible to search for dark matter solely vi…
First Search for Ultralight Dark Matter Using a Magnetically Levitated Particle
Dorian W. P. Amaral, Dennis G. Uitenbroek, Tjerk H. Oosterkamp +1
We perform the first search for ultralight dark matter using a magnetically levitated particle. A sub-millimeter permanent magnet is levitated in a superconducting trap with a meas…
Approximate Differentiable Likelihoods for Astroparticle Physics Experiments
Juehang Qin, Christopher Tunnell
Traditionally, inference in liquid xenon direct detection dark matter experiments has used estimators of event energy or density estimation of simulated data. Such methods have dra…
Fast Bayesian Inference for Neutrino Non-Standard Interactions at Dark Matter Direct Detection Experiments
Dorian W. P. Amaral, Shixiao Liang, Juehang Qin +1
Multi-dimensional parameter spaces are commonly encountered in physics theories that go beyond the Standard Model. However, they often possess complicated posterior geometries that…
Vector Wave Dark Matter and Terrestrial Quantum Sensors
Dorian W. P. Amaral, Mudit Jain, Mustafa A. Amin +1
(Ultra)light spin- particles -- dark photons -- can constitute all of dark matter (DM) and have beyond Standard Model couplings. This can lead to a coherent, oscillatory signatu…
GPU-based optical simulation of the DARWIN detector
L. Althueser, B. Antunović, E. Aprile +77
Understanding propagation of scintillation light is critical for maximizing the discovery potential of next-generation liquid xenon detectors that use dual-phase time projection ch…
Domain-informed neural networks for interaction localization within astroparticle experiments
Shixiao Liang, Aaron Higuera, Christina Peters +4
This work proposes a domain-informed neural network architecture for experimental particle physics, using particle interaction localization with the time-projection chamber (TPC) t…
SNEWS 2.0: A Next-Generation SuperNova Early Warning System for Multi-messenger Astronomy
S. Al Kharusi, S. Y. BenZvi, J. S. Bobowski +68
The next core-collapse supernova in the Milky Way or its satellites will represent a once-in-a-generation opportunity to obtain detailed information about the explosion of a star a…
