Vortex clusters and vortex-filled bubbles in a modified Abelian-Higgs model
D. Miguélez-Caballero, S. Navarro-Obregón, Muneto Nitta +1
We investigate a single-component Abelian-Higgs model with an eighth-order scalar potential whose vacuum manifold consists of two disconnected circles. The model supports two speci…
Impact of the internal modes on the sphaleron decay
S. Navarro-Obregón, J. Queiruga
We study the sphaleron solutions in two deformations of the model and analyze the oscillons originated from them. We find that the presence of internal modes plays a crucial…
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…
