Localized Vector Modes on Local Cosmic Strings
Sergio Alameda-Calvo, Jose J. Blanco-Pillado, Jose Queiruga
We investigate the dynamics of vector excitations localized on cosmic strings in the Abelian-Higgs model. These confined gauge field fluctuations behave as massive vector degrees o…

On curvature corrections for field theory cosmic strings
Josu C. Aurrekoetxea, Jose J. Blanco-Pillado, Alberto García Martín-Caro +1
We present a combined analytical and numerical study of the effective action of field theory cosmic strings in the Abelian-Higgs model in flat space. Starting directly from the und…
