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…
Electroweak form factors of large nuclei as BPS skyrmions
Alberte Xosé López Freire, Christoph Adam, Alberto García Martín-Caro +1
We employ the Bogomolnyi-Prasad-Sommerfield (BPS) Skyrme model within the framework of semi-classical quantization as an effective model to compute both the electromagnetic and neu…
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…
