Search for a solar-bound axion halo using the Global Network of Optical Magnetometers for Exotic physics searches
Tatum Z. Wilson, Derek F. Jackson Kimball, Samer Afach +50
We report on a search for a gravitationally bound solar axion halo using data from the Global Network of Optical Magnetometers for Exotic physics searches (GNOME), a worldwide arra…
Frequency-scanning considerations in axionlike dark matter spin-precession experiments
Yuzhe Zhang, Deniz Aybas Tumturk, Hendrik Bekker +4
Galactic dark matter may consist of axionlike particles (ALPs) that can be described as an "ultralight bosonic field" oscillating at the ALP Compton frequency. The ALP field can be…
Measurement of the ratio between g-factors of the ground states of Rb and Rb
Jason Mora, Aracely Cobos, Dominic Fuentes +1
The ratio between the Landé g-factors of the Rb and Rb ground state hyperfine levels is experimentally measured to be , co…
Nuclear-spin comagnetometer based on a liquid of identical molecules
Teng Wu, John W. Blanchard, Derek F. Jackson Kimball +2
Atomic comagnetometers are used in searches for anomalous spin-dependent interactions. Magnetic field gradients are one of the major sources of systematic errors in such experiment…
Constraints on exotic spin-dependent interactions between matter and antimatter from antiprotonic helium spectroscopy
Filip Ficek, Pavel Fadeev, Victor V. Flambaum +4
Heretofore undiscovered spin-0 or spin-1 bosons can mediate exotic spin-dependent interactions between standard-model particles. Here we carry out the first search for semileptonic…
Searching for axion stars and Q-balls with a terrestrial magnetometer network
D. F. Jackson Kimball, D. Budker, J. Eby +6
Light (pseudo-)scalar fields are promising candidates to be the dark matter in the Universe. Under certain initial conditions in the early Universe and/or with certain types of sel…
