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…
Pulsar Consensus
Samer Afach, Benjamin Marsh, Enrico Rubboli
In this paper, we informally introduce the Pulsar proof of stake consensus paper and discuss the relevant design decisions and considerations. The Pulsar protocol we propose is des…
A Multi-Messenger Search for Exotic Field Emission with a Global Magnetometer Network
Sami S. Khamis, Ibrahim A. Sulai, Paul Hamilton +38
Quantum sensor networks in combination with traditional astronomical observations are emerging as a novel modality for multi-messenger astronomy. Here we develop a generic analysis…
What can a GNOME do? Search targets for the Global Network of Optical Magnetometers for Exotic physics searches
S. Afach, D. Aybas Tumturk, H. Bekker +50
Numerous observations suggest that there exist undiscovered beyond-the-Standard-Model particles and fields. Because of their unknown nature, these exotic particles and fields could…
Search for topological defect dark matter with a global network of optical magnetometers
Samer Afach, Ben C. Buchler, Dmitry Budker +46
Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the form of topological defects that…
Search for axion-like dark matter using solid-state nuclear magnetic resonance
Deniz Aybas, Janos Adam, Emmy Blumenthal +22
We report the results of an experimental search for ultralight axion-like dark matter in the mass range 162 neV to 166 neV. The detection scheme of our Cosmic Axion Spin Precession…
Characterization of the Global Network of Optical Magnetometers to search for Exotic Physics (GNOME)
S. Afach, D. Budker, G. DeCamp +21
The Global Network of Optical Magnetometers to search for Exotic physics (GNOME) is a network of geographically separated, time-synchronized, optically pumped atomic magnetometers…
Overview of the Cosmic Axion Spin Precession Experiment (CASPEr)
D. F. Jackson Kimball, S. Afach, D. Aybas +15
An overview of our experimental program to search for axion and axion-like-particle (ALP) dark matter using nuclear magnetic resonance (NMR) techniques is presented. An oscillating…
A Method for Measurement of Spin-Spin Couplings with sub-mHz Precision Using Zero- to Ultralow-Field Nuclear Magnetic Resonance
Alexander Wilzewski, Samer Afach, John W. Blanchard +1
We present a method which allows for the extraction of physical quantities directly from zero- to ultralow-field nuclear magnetic resonance (ZULF NMR) data. A numerical density mat…
Microwave-free magnetometry with nitrogen-vacancy centers in diamond
Arne Wickenbrock, Huijie Zheng, Lykourgos Bougas +5
We use magnetic-field-dependent features in the photoluminescence of negatively charged nitrogen-vacancy centers to measure magnetic fields without the use of microwaves. In partic…
