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…

Sphaleron decay on circles
S. Navarro-Obregón, J. Queiruga
We discuss various sphaleron-like solutions on . These solutions are static, but unstable. We explore possible stabilization mechanisms based on the excitation of int…
