Detecting Axion Dark Matter with an Organic Molecular Maser
Abstract
We present a novel quantum sensing approach to search for axion-electron interactions around the axion mass of 6 μeV. In this region, laboratory searches are relatively scarce, and our direct experiment measuring the axion-electron coupling constant reaches the sensitivity of 8 × 10-6 GeV-1. The method, based on an organic molecular maser establishes a proof-of-principle for quantum-enhanced detection, with a corresponding magnetic field sensitivity of 0.85 fT/Hz. The methodology is generic and can be readily extended to other physical systems, further broadening its applicability in quantum sensing and dark matter searches.
