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…
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…
Hybrid optical pumping of K and Rb atoms in a paraffin coated vapor cell
Wenhao Li, Xiang Peng, Dmitry Budker +4
Dynamic hybrid optical pumping effects with a radio-frequency-field-driven nonlinear magneto-optical rotation (RF NMOR) scheme are studied in a dual-species paraffin coated vapor c…
Suppression of nonlinear Zeeman effect and heading error in earth-field-range alkali-vapor magnetometers
Guzhi Bao, Arne Wickenbrock, Simon Rochester +1
The nonlinear Zeeman effect can induce splitting and asymmetries of magnetic-resonance lines in the geophysical magnetic field range. This is a major source of "heading error" for…
The Cosmic Axion Spin Precession Experiment (CASPEr): a dark-matter search with nuclear magnetic resonance
Antoine Garcon, Deniz Aybas, John W. Blanchard +12
The Cosmic Axion Spin Precession Experiment (CASPEr) is a nuclear magnetic resonance experiment (NMR) seeking to detect axion and axion-like particles which could make up the dark…
Miniature cavity-enhanced diamond magnetometer
Georgios Chatzidrosos, Arne Wickenbrock, Lykourgos Bougas +5
We present a highly sensitive miniaturized cavity-enhanced room-temperature magnetic-field sensor based on nitrogen-vacancy (NV) centers in diamond. The magnetic resonance signal i…
Network of sensitive magnetometers for urban studies
T. A. Bowen, E. Zhivun, A. Wickenbrock +6
The magnetic signature of an urban environment is investigated using a geographically distributed network of fluxgate magnetometers deployed in and around Berkeley, California. The…
Level anti-crossing magnetometry with color centers in diamond
Huijie Zheng, Georgios Chatzidrosos, Arne Wickenbrock +7
Recent developments in magnetic field sensing with negatively charged nitrogen-vacancy centers (NV) in diamond employ magnetic-field (MF) dependent features in the photoluminescenc…
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…
