Spectral structure of fluctuations around -vortices in the Abelian-Higgs model
A. Alonso-Izquierdo, D. Miguélez-Caballero, J. Queiruga
We study in detail the internal structure of rotationally invariant higher-charge Abelian-Higgs vortices. The symmetry of the normal modes close to the critical regime for type II…

Moduli space metric of the excited vortex
D. Miguélez-Caballero, S. Navarro-Obregón, A. Wereszczynski
We show that the moduli space metric of a single vortex gets corrections because of the excitation of the radially symmetric shape mode. It leads to a non-zero amount of the shape…

Scattering between orthogonally wobbling kinks
A. Alonso-Izquierdo, D. Miguélez-Caballero, L. M. Nieto
The resonant energy transfer mechanism, responsible for the presence of fractal patterns in the velocity diagrams of kink-antikink scattering, is analyzed for a family of two-compo…
