Scattering of wobbling vortices
A. Alonso-Izquierdo, A. González-Parra, A. Wereszczynski
We investigate the dynamical role of internal vibrational modes in the Abelian Higgs model, focusing on how Derrick-type excitations modify vortex dynamics and scattering processes…

Oscillons in the broken vacuum and global vortex annihilation
D. Canillas Martínez, A. González-Parra, D. Miguélez-Caballero +1
In contrast to the complex model, vortex-antivortex collisions in the complex theory reveal a resonant structure due to the existence of a remarkably stable, long-lived…

BPS and semi-BPS kink families in two-component scalar field theories with fourth-degree polynomial potentials
A. Alonso-Izquierdo, M. A. González León, A. González-Parra +1
We perform a systematic study of kink solutions in two-component scalar field theories in dimensions with interaction terms of at most quartic order. Our approach is based…
