| contents | We study the dynamics of Abelian-Higgs vortices in the background of a coherently oscillating axion field. We show that the electric field is induced in the magnetic core of the vortex due to the axion-photon conversion. Moreover, because the electromagnetic field is confined in the vortex and excluded from the superconducting bulk regions due to the Meissner effect, the vortex tube can be regarded as a cylindrical cavity, and our numerical analysis shows that the resonant cavity mode (TM010 mode) can be efficiently enhanced in this tube. We also focus on the interaction of two vortices in the oscillating axion background, resulting in attractive or repulsive forces, even in the case with the BPS limit. These new features open up a new possibility for the axion dark matter search using superconducting devices. |
