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…
Cuspidal Singularities in Collapsing Domain Walls
Jose J. Blanco-Pillado, Matthew Elley, Francesc Ferrer +4
Domain wall networks have attracted renewed interest, particularly in relation to the dynamics of network collapse. Accurately describing this process is challenging and typically…
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…
Quantum fermion emission from excited kinks
Sergio Alameda-Calvo, Jose J. Blanco-Pillado, Alberto García Martín-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…
From Cusps to Swallowtails: Domain Wall singularities in 2+1 dimensions
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Oriol Pujolàs
The effective Nambu-Goto description of -dimensional domain walls predicts singular behavior of its worldsheet resulting in swallowtail bifurcations. This phenomenon is inti…
