Abstract

The axion were proposed as a result to a solution to the Strong CP Problem in quantum chromodynamics (QCD) and is now considered a leading candidate for dark matter. Direct axion dark matter detection experiments are challenging due to the axion's weak interaction with electromagnetism. Recent work has suggested the possibility of an enhancement of astrophysical axion-to-photon decay through parametric resonance. We explore here the feasibility of using parametric resonance to enhance the signal in direct axion-like particle dark matter detectors.
