WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record compiled from open scholarly databases; the abstract is shown in full only where the paper is openly licensed, otherwise a short excerpt under fair use. Classifications are automated and approximate.

The ever-increasing number of detections of gravitational waves from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensitive tests of general relativity (GR) in the dynamical and…

We perform the first search for ultralight dark matter using a magnetically levitated particle. A submillimeter permanent magnet is levitated in a superconducting trap with a measured force sensitivity of 0.2 fN/sqrt[Hz]. We find no evidence of a signal and derive limits on dark matter coupled to the difference between baryon and lepton number, B-L, in the mass range (1.10360-1.10485)×10^{-13} eV/c^{2}. Our most stringent limit on the coupling strength is g_{B-L}≲2.98×10^{-21}. We propose the POLONAISE (Probing Oscillations using Levitated Objects for Novel Accelerometry In Searches of Exotic
