Type I-II/II-I vortices from dimension-six self-interaction
A. Alonso-Izquierdo, A. González-Parra, K. Slawinska +2
We show that adding a dimension-six self-interaction to the Abelian-Higgs or Ginzburg Landau model results in a remarkable and rich structure of multi-vortex solutions. Besides the…
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 and bubbles in -ball dynamics
D. Canillas Martínez, P. Dorey, T. Romańczukiewicz +3
We show that, in the thin-wall regime, -ball--anti--ball collisions reveal chaotic behaviour. This is explained by the resonant energy transfer mechanism triggered by the int…
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…
Dynamics of Excited BPS 3-Vortices
A. Alonso-Izquierdo, N. S. Manton, J. Mateos Guilarte +2
We analyze the dynamics of BPS 3-vortex solutions. First, for unexcited vortices, we study the 2-dimensional moduli space of centred vortices with symmetry, and its metr…
Stability and decay of composite kinks/-balls solutions in a deformed linear sigma model
A. Alonso-Izquierdo, D. Canillas Martinez, C. Garzon Sanchez +2
The defect-type solutions of a deformed linear sigma model with a real and complex fields in -dimensional Minkowski spacetime are studied. All the solutions ar…
