We propose new signals for the direct detection of ultralight dark matter such as the axion. Axion or axionlike particle dark matter may be thought of as a background, classical field. We consider couplings for this field which give rise to observable effects including a nuclear electric dipole moment, and axial nucleon and electron moments. These moments oscillate rapidly with frequencies accessible in the laboratory, ∼ kilohertz to gigahertz, given by the dark matter mass. Thus, in contrast…

Revealing the dark matter halo with axion direct detection
The next generation of axion direct detection experiments may rule out or confirm axions as the dominant source of dark matter. We develop a general likelihood-based framework for studying the
Axion dark matter detection with CMB polarization
We point out two ways to search for low-mass axion dark matter using cosmic microwave background (CMB) polarization measurements. These appear, in particular, to be some of the most promising ways to
LC Circuits for the Direct Detection of Ultralight Dark Matter Candidates
Cosmological mechanisms that yield ultralight dark matter are insensitive to the intrinsic parity of a bosonic dark matter candidate, but that same quantity plays a crucial role in a direct detection
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 C P -odd nuclear moments
Manifestations of dark matter and variations of fundamental constants in atoms and astrophysical phenomena
We present an overview of recent developments in the detection of light bosonic dark matter, including axion, pseudoscalar axion-like and scalar dark matter, which form either a coherently
Detecting dark blobs
Current dark matter detection strategies are based on the assumption that the dark matter is a gas of non-interacting particles with a reasonably large number density. This picture is dramatically
The Cosmic Axion Spin Precession Experiment (CASPEr): a dark-matter search with nuclear magnetic resonance
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 matter present in
Searching for dark matter with atomic clocks and laser interferometry
We propose new schemes for the direct detection of low-mass dark matter with atomic clock and laser interferometry experiments. Dark matter, which consists of low-mass bosons, can readily form an
Search for Axionlike Dark Matter through Nuclear Spin Precession in Electric and Magnetic Fields
We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spinprecession frequencies of stored ultracold neutrons and 199Hg atoms for an axion-induced oscillating
Broadband and Resonant Approaches to Axion Dark Matter Detection.
TLDR
This work considers both resonant and broadband readout circuits and shows that a broadband approach has advantages at small axion masses, and demonstrates potential sensitivity to axionlike dark matter with masses in the range of 10^{-14}-10^{-6}  eV.
