Axions and axionlike particles are strongly motivated dark-matter candidates that are the subject of many current ground based dark-matter searches. We present first results from the Axion Dark-Matter Birefringent Cavity (ADBC) experiment, which is an optical bow-tie cavity probing the axion-induced birefringence of electromagnetic waves. Our experiment is the first optical axion detector that is tunable and quantum noise limited, making it sensitive to a wide range of axion masses. We have iteratively probed the axion mass ranges 40.9-43.3  neV/c^{2}, 49.3-50.6  neV/c^{2}, and 54.4-56.7  neV/c^{2}, and found no dark-matter signal. On average, we constrain the axionlike particle and photon coupling at the level g_{aγγ}≤1.9×10^{-8}  GeV^{-1}. We also present prospects for future axion dark-matter detection experiments using optical cavities.

The existence of light QCD axions, whose mass depends on an additional free parameter, can lead to a new ground state of matter, where the sourced axion field reduces the nucleon effective mass. The presence of the axion field has structural consequences, in particular, it results in a thinner (or even prevents its existence) heat-blanketing envelope, significantly altering the cooling patterns of neutron stars. We exploit the anomalous cooling behavior to constrain previously uncharted regions of the axion parameter space by comparing model predictions with existing data from isolated neutron stars.

We give for the first time theoretical estimates of unknown rare electron-capture (EC) decay branchings of ^{44}Ti, ^{57}Co, and ^{139}Ce, relevant for searches of (exotic) dark-matter particles. The nuclear-structure calculations have been done exploiting the nuclear shell model with well-established Hamiltonians and an advanced theory of β decay. In the absence of experimental measurements of these rare branches, these estimates are of utmost importance for terrestrial searches of dark-matter particles, such as axionic dark matter in the form of axionlike particles, anapole dark matter, and dark photons in nuclear transitions.

Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope has been searching for solar axions via their back conversion to x-ray photons in a 9-T 10-m long magnet directed toward the Sun. We report on an extended run with the International Axion Observatory pathfinder detector, doubling the previous exposure time.

Article Synopsis
  • As the search frequency for axions increases, detection efficiency drops due to reduced cavity volume, although higher-order resonant modes could help maintain volume.
  • A new tuning method using auxetic materials was introduced to improve detection, successfully applied to a specific mode, leading to new limits on axion-photon coupling strength in a targeted mass range.

Article Synopsis
  • Axions are theoretical particles that might explain dark matter and a specific physics problem (strong CP problem), and this study investigates their interactions using ^{129}Xe gas and Rb vapor.
  • The method used enhances the detection sensitivity for these axion interactions by 145 times compared to traditional approaches through magnetic amplification and effective field exploitation.
  • The research led to significant improvements in constraints on interactions related to axions, expanding the search for these particles and their potential links to dark matter, with implications for future investigations in this field.
