Proposal for a Cosmic Axion Spin Precession Experiment (CASPEr)
Proposal for a Cosmic Axion Spin Precession Experiment (CASPEr)
We propose an experiment to search for QCD axion and axionlike-particle dark matter. Nuclei that are interacting with the background axion dark matter acquire time-varying CP-odd nuclear moments such as an electric dipole moment. In analogy with nuclear magnetic resonance, these moments cause precession of nuclear spins in a material …
