| Popis: | The ultralight dark matter (ULDM) such as axion or wavelike scalar plays as a plausible DM candidate. Recently, the possible non-standard ULDM couplings draw much attention. In this work we investigate the detection of electromagnetic couplings in a few benchmark models of ULDM. For illustration, we consider the generic axion electrodynamics including CP violating coupling as well as the newly proposed axion electromagnetodynamics. The superconducting radio frequency (SRF) cavity with two-mode has more advantages than the traditional cavity approach with static background field. We utilize the two-mode SRF cavity to probe the generic couplings of ULDM with frequency lower than GHz. The choices of the transverse electromagnetic modes are explicitly specified for the detection. We show the sensitivity of the SRF cavity to the axion couplings in the above frameworks.
