“…Microwave photon detection and cavity design have allowed the haloscope concept to break ground to exclude regions of the QCD axion parameter space and expand the search over a wider frequency range ( 33 – 35 ). In tandem, new methods to detect axions have been conceived of and developed, including magnetic resonance ( 31 , 36 – 39 ), broadband antennas ( 40 ), dielectrics and metamaterials ( 41 , 42 ), and lumped circuit technology ( 43 , 44 ). These new technologies are at various stages of maturity, with some only existing on paper, others being prototyped, and others already making competitive measurements of axion parameter space and excluding theoretical models.…”

The axion has emerged in recent years as a leading particle candidate to provide the mysterious dark matter in the cosmos, as we review here for a general scientific audience. We describe first the historical roots of the axion in the Standard Model of particle physics and the problem of charge-parity invariance of the strong nuclear force. We then discuss how the axion emerges as a dark matter candidate and how it is produced in the early universe. The symmetry properties of the axion dictate the form of its interactions with ordinary matter. Astrophysical considerations restrict the particle mass and interaction strengths to a limited range, which facilitates the planning of experiments to detect the axion. A companion review discusses the exciting prospect that the axion could be detected in the near term in the laboratory.

“…In Table .I, we compare our form factor C with those of ABRACADABRA (ABRA.) [15,[17][18][19] and SHAFT [16] among other experiments that conduct axion search with SQUID magnetometer with various geometries of magnets and pickup loops. By virtue of the large volume and high magnetic field strength of our magnets, the expected C parameter for WISPLC is about three orders of magnitude larger than those for the other experiments listed.…”

The focus on dark matter search has expanded to include low-mass particles such as axions or axion-like particles, and novel theoretical schemes extending the phenomenological landscape, within QCD and beyond, also garnered additional interest in recent decades. Assuming dark matter is composed of axions, in presence of a solenoidal magnetic field, they induce a displacement current that gives rise to a toroidal magnetic field. The Weakly Interacting Slender Particle detection with LC circuit (WISPLC) is a precision direct detection experiment that will search for light dark matter candidates such as axion-like particles in parts of the parameter space previously unexplored. We present two detection schemes of the signal in a pickup loop capturing the flux of this toroidal magnetic field. WISPLC operates in a broadband and a resonant scheme where a LC circuit is used to enhance the signal with an expected Q factor ∼ 10 4 . Taking into account the irreducible flux noise of the detector, we estimate the sensitivity of the experiment in the axion mass range between 10 −11 eV and 10 −6 eV to reach a detectable axion-photon coupling of gaγγ ≈ 10 −15 GeV −1 , making it possible to probe mass ranges corresponding to ultralight axions motivated by string theory. The WISPLC experiment is fully funded and currently in the construction phase.

“…The blue (red) lines represent the designed shot noise limited sensitivity of DANCE Act-1 (DANCE) with feasible (optimistic) parameters if we observe for a year. The grey lines with shaded region are current bounds obtained from CAST [13], SHAFT [14], and ABRACADABRA-10cm [15] experiments, and the astrophysical constraints from the gamma-ray observations of SN1987A [16] and the X-ray observations of NGC1275 galaxy [17].…”

Dark matter Axion search with riNg Cavity Experiment (DANCE) was proposed to search for axion dark matter [Phys. Rev. Lett. 121, 161301 (2018)]. We aim to detect the rotation and oscillation of optical linear polarization caused by axion-photon coupling with a bow-tie cavity. DANCE can improve the sensitivity to axion-photon coupling constant gaγ for axion mass ma < 10 −10 eV by several orders of magnitude compared to the best upper limits at present. A prototype experiment DANCE Act-1 is ongoing to demonstrate the feasibility of the method and to investigate technical noises. The optics was assembled and the performance of the cavity was evaluated. The first 12-day observation was successfully performed in May 2021. We reached 3 × 10 −6 rad/ √ Hz at 10 Hz in the one-sided amplitude spectral density of the rotation angle of linear polarization.
