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…
Physics-informed continuous normalizing flows to learn the electric field within a time-projection chamber
Ivy Li, Peter Gaemers, Juehang Qin +4
Accurate position reconstruction in noble-element time-projection chambers (TPCs) is critical for rare-event searches in astroparticle physics, yet is systematically limited by ele…
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…
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…
Mechanical Quantum Sensing in the Search for Dark Matter
Daniel Carney, Gordan Krnjaic, David C. Moore +32
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matt…
