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…
