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…
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…
Excited oscillons and charge-swapping
A. Alonso-Izquierdo, D. Canillas Martínez, T. Romańczukiewicz +2
We show that the charge-swapping phenomenon can be understood as a real valued oscillon carrying an excitation in imaginary direction in the target space. Furthermore, we introduce…
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…
Transference of kinks between and Sigma models
A. Alonso-Izquierdo, A. J. Balseyro Sebastian, M. A. Gonzalez Leon
In this paper methods for deforming scalar field theories on Euclidean target spaces, in which new field theories are constructed so that solutions are known, are generalized to th…
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…
Excited Abelian-Higgs vortices: decay rate and radiation emission
A. Alonso-Izquierdo, J. J. Blanco-Pillado, D. Miguélez-Caballero +2
The evolution of 1-vortices when their massive bound mode is excited is investigated in detail (both analytically and numerically) in the Abelian-Higgs model for different ranges o…
Semi-BPS sphaleron and its dynamics
A. Alonso-Izquierdo, S. Navarro-Obregón, K. Oles +3
We construct a simple field theory in which a sphaleron, i.e., a saddle-point particle-like solution, forms a semi-BPS state with a background defect that is an impurity. This mean…
