Self-field of a moving string

Richard A. Battye, Lukasz P. Bunio, Steven J. Cotterill

We discuss the effectiveness of the recently proposed quantity in suppressing the contribution of a string's self-field to its spectrum, which is used in field theory simul…

Kinky vortons in the 2HDM

Richard A. Battye, Steven J. Cotterill, Adam K. Thomasson

We construct and analyse two-dimensional, current-carrying ring solutions, known as kinky vortons, in the -symmetric global two-Higgs-doublet model (2HDM). We demonst…

Spectrum of radiation from global strings and the relic axion density

Richard A. Battye, Lukasz P. Bunio, Steven J. Cotterill +1

We discuss key aspects of the nature of radiation from global strings and its impact on the relic axion density. Using a simple model we demonstrate the dependence on the spectrum…

Vortex stability in pseudo-Hermitian theories

R. A. Battye, S. J. Cotterill, P. Millington

Pseudo-Hermitian (including -symmetric) field theories support phenomenology that cannot be replicated in standard Hermitian theories. We describe a concrete example…

Complete Classification of Domain Wall Solutions in the -symmetric 2HDM

Richard A. Battye, Steven J. Cotterill, Adam K. Thomasson

We present a complete classification of domain wall solutions in the two-Higgs Doublet Model (2HDM) with a global symmetry, categorised as superconducting, CP-violat…

Near-Peak Spectrum of Gravitational Waves from Collapsing Domain Walls

Bryce Cyr, Steven Cotterill, Richard Battye

Cosmological domain walls appear in many well-motivated extensions to the standard model of particle physics. If produced, they quickly enter into a self-similar scaling regime, wh…

Percolation of Domain Walls in the Two-Higgs Doublet Model

Richard A. Battye, Steven J. Cotterill, Eva Sabater Andres +1

Domain walls formed during a phase transition in a simple field theory model with symmetry in a periodic box have been demonstrated to annihilate as fast as causalit…

Superconducting strings in the two-Higgs doublet model

Richard Battye, Steven Cotterill

We present superconducting vortex solutions in the two-Higgs doublet model which has a gauged Higgs-family symmetry. We write down an ansatz for the solution and study its b…

Spontaneous Hopf fibration in the two-Higgs-doublet model

R. A. Battye, S. J. Cotterill

We show that energetic considerations enforce a Hopf fibration of the Standard Model topology within the 2HDM whose potential has either an or Higgs-family symmetry.…

Global monopoles in the two-Higgs-doublet-model

Richard A. Battye, Steven J. Cotterill, Dominic G. Viatic

We discuss monopoles formed due to the spontaneous breakdown of a global symmetry within the global two-Higgs doublet model. We explain that the Higgs sector dynam…

Pinching instabilities in superconducting strings

R. A. Battye, S. J. Cotterill

Superconducting cosmic strings can exhibit longitudinal, pinching instabilities in some regions of the parameter space. We make predictions about the onset of this instability usin…

A detailed study of the stability of vortons

R. A. Battye, S. J. Cotterill, J. A. Pearson

We construct and simulate the dynamics of gauged vortons - circular loops of cosmic string supported by the angular momentum of trapped charge and current and provide additional de…

Stable cosmic vortons in bosonic field theory

R. A. Battye, S. J. Cotterill

Stable ring solutions supported by the angular momentum caused by superconducting charge and current have been suggested to exist in the gauged field theory. We c…
