Dark Matter Axion Search Using a Josephson Traveling Wave Parametric Amplifier

C. Bartram, T. Braine, R. Cervantes +48

We present a new exclusion bound of axion-like particle dark matter with axion-photon couplings above $10^{-13}$ $\mathrm{Ge}{\mathrm{V}}^{-1}$ over the frequency range 4796.7--4799.…
