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…

Quantum fermion emission from excited kinks
Sergio Alameda-Calvo, Jose J. Blanco-Pillado, Alberto GarcÃa MartÃn-Caro
The amplitude of an excited shape mode in a kink is expected to decay with a well-known power law via scalar radiation emission due to the nonlinear self-coupling of the scalar fie…
