Unified origin of axion and monopole dark matter, and solution to the domain-wall problem
We propose a scenario in which the spontaneous breakdown of the Peccei-Quinn symmetry leads to monopole production. Both the axion and the monopole contribute to dark matter, and the Witten effect on the axion mass is a built-in feature. In the Kim-Shifman-Vainshtein-Zakharov-type axion model, seemi...
