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…

Ito calculus meets the Hubble tension: Effects of small-scale electron density fluctuations on the CMB anisotropies
Jens Chluba, Geoffrey Vasil, Richard Battye
In this work, we develop a novel formalism to include the effect of electron density fluctuations at ultra small scales (well below the sound horizon at last scattering) on the obs…

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…
