Searching for invisible axion dark matter with a new multiple-cell cavity haloscope

Figure showing the cross-sectional view of various multiple-cell (double-, quadruple-, and octuple-cell) cavities with the expected distribution of the axion-induced electric field by the resonant mode of interest. Credit: Jeong et al. Over the past few decades, many experimental physicists have been probing the existence of particles called axions, which would result from a specific […]
