Momentum Flux for Small-Amplitude Oscillons
N. S. Manton, Azadeh Mohammadi
An oscillon in scalar field theory in -dimensions is an oscillating, localised, almost periodic classical solution that slowly radiates and decays to the vacuum solution. We…
Vortex-Antivortex Annihilation from BPS Equations
J. P. S. Neto, J. G. F. Campos, A. Mohammadi
In this work, we introduce a vortex-impurity model that admits BPS configurations containing both vortices and antivortices and allows vortex-antivortex annihilation to be describe…
Collision Dynamics of False-Vacuum Oscillons
J. G. F. Campos, N. S. Manton, Azadeh Mohammadi
We study the collision dynamics of localized oscillons in two classes of -dimensional scalar field theories with metastable false vacua, a normal class with a positive quart…
Generalized BPS magnetic monopoles in inhomogeneous Yang-Mills-Higgs models
Filipe Rodrigues da Silva, Azadeh Mohammadi
We present a non-Abelian model for magnetic monopoles in inhomogeneous media, based on a generalization of the standard 't~Hooft-Polyakov model. The medium is described by spatiall…
