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…
Universal determination of comagnetometer response to spin couplings
Mikhail Padniuk, Emmanuel Klinger, Grzegorz Lukasiewicz +6
We propose and demonstrate a general method to calibrate the frequency-dependent response of self-compensating noble-gas-alkali-metal comagnetometers to arbitrary spin perturbation…
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…
Optimization of nuclear polarization in an alkali-noble gas comagnetometer
Emmanuel Klinger, Tianhao Liu, Mikhail Padniuk +6
Self-compensated comagnetometers, employing overlapping samples of spin-polarized alkali and noble gases (for example K-He) are promising sensors for exotic beyond-the-standard…
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…
Application of Spin-Exchange Relaxation-Free Magnetometry to the Cosmic Axion Spin Precession Experiment
Tao Wang, Derek F. Jackson Kimball, Alexander O. Sushkov +7
The Cosmic Axion Spin Precession Experiment (CASPEr) seeks to measure oscillating torques on nuclear spins caused by axion or axion-like-particle (ALP) dark matter via nuclear magn…
Constraints on exotic spin-dependent interactions between electrons from helium fine-structure spectroscopy
Filip Ficek, Derek F. Jackson Kimball, Mikhail Kozlov +3
Agreement between theoretical calculations of atomic structure and spectroscopic measurements is used to constrain possible contribution of exotic spin-dependent interactions betwe…
Constraints on exotic dipole-dipole couplings between electrons at the micrometer scale
Shlomi Kotler, Roee Ozeri, Derek F. Jackson Kimball
New constraints on exotic dipole-dipole interactions between electrons at the micrometer scale are established, based on a recent measurement of the magnetic interaction between tw…
Nuclear spin content and constraints on exotic spin-dependent couplings
D. F. Jackson Kimball
There are numerous recent and ongoing experiments employing a variety of atomic species to search for couplings of atomic spins to exotic fields. In order to meaningfully compare t…
A dual-isotope rubidium comagnetometer to search for anomalous long-range spin-mass (spin-gravity) couplings of the proton
D. F. Jackson Kimball, I. Lacey, J. Valdez +7
The experimental concept of a search for a long-range coupling between rubidium (Rb) nuclear spins and the mass of the Earth is described. The experiment is based on simultaneous m…
