Phase transition dynamics of Abelian-Higgs vortices in the oscillating axion background
Naoya Kitajima, Shota Nakagawa
We investigate the effect of an oscillating axion background on thermally induced vortex-antivortex production in the Abelian-Higgs model. Through its coupling to the gauge field,…

Multimodal axion emissions from Abelian-Higgs cosmic strings
Naoya Kitajima, Michiru Uwabo-Niibo
We show that axions can be produced from Abelian-Higgs cosmic strings due to the axion-gauge coupling. The strong magnetic field is confined in the string, and the electric field i…

Abelian-Higgs vortices in the oscillating axion background
Naoya Kitajima, Shota Nakagawa
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 vo…
