Description

Axion and Dark Photon (DP) have been considered as well-motivated dark matter candidates. Both hypothetical particles, if exist, are characterized by extremely feeble interactions with photons, rendering them suitable candidates for direct dark matter detection.
In this presentation, we introduce a new experimental strategy aimed at the detection of both axions and Dark Photons. This approach uses coherent atoms as target, where Axions/DPs induce resonant atomic transitions, accompanied by the emission of signal photons for detection. The key feature of this method is the “coherent amplification”. That is, when the process occurs coherently in an N-atom system, its transition amplitude interferes constructively and the rate becomes proportional to N square instead of N. This remarkable amplification effect holds significant promise and is poised to provide stringent constraints on the Axion-Photon coupling constant and DP mixing parameter within the meV mass range.
