Negative Baryon density and the Folding structure of the B=3 Skyrmion [PDF]

, 2013
The Skyrme model is a non-linear field theory whose solitonic solutions, once quantised, describe atomic nuclei. The classical static soliton solutions, so-called Skyrmions, have interesting symmetries and can only be calculated numerically ...

Dynamically assisted Sauter-Schwinger effect — non-perturbative versus perturbative aspects

Journal of High Energy Physics, 2017
The Sauter-Schwinger effect predicts the creation of electron-positron pairs out of the quantum vacuum by a strong and slowly varying electric field.

Dynamics of vortices with magnetic impurities [PDF]

, 2017
We investigate the dynamics of BPS vortices in the presence of magnetic impurities taking the form of axially-symmetric localised lumps and delta-functions. We present numerical results for vortices on flat space, as well as exact results for vortices on

Abelian Chern-Simons vortices at finite chemical potential

Journal of High Energy Physics, 2020
We examine vortices in Abelian Chern-Simons theory coupled to a relativistic scalar field with a chemical potential for particle number or U(1) charge.

Bogomol’nyi equations on constant curvature spaces [PDF]

, 2004
This thesis is concerned with the anti-self-dual Yang-Mills equations and their reductions to Bogomol’nyi equations on constant curvature spaces. Chapters 1 and 2 contain introductory material.

Moduli spaces of instantons in flag manifold sigma models. Vortices in quiver gauge theories

Journal of High Energy Physics
In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma models. In particular, we focus on the moduli space of BPS lumps in general Kähler flag manifold sigma models. Such a Kähler flag manifold, which takes the form U n 1 + ⋯ + n

Oscillons and bubbles in Q-ball dynamics

Journal of High Energy Physics
We show that, in the thin-wall regime, Q-ball-anti-Q-ball collisions reveal chaotic behaviour. This is explained by the resonant energy transfer mechanism triggered by the internal modes hosted by the Q-balls and by the existence of ephemeral states ...

A supersymmetric exotic field theory in (1+1) dimensions: one loop soliton quantum mass corrections

Journal of High Energy Physics, 2018
We consider one loop quantum corrections to soliton mass for the N = 1 $$ \mathcal{N}=1 $$ supersymmetric extension of the (1+1)-dimensional scalar field theory with the potential U (ϕ) = ϕ 2 cos2 (ln ϕ 2).

Excited oscillons and charge-swapping

Journal of High Energy Physics
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.
