Axion strings are superconducting

Journal of High Energy Physics, 2021
We explore the cosmological consequences of the superconductivity of QCD axion strings. Axion strings can support a sizeable chiral electric current and charge density, which alters their early universe dynamics. We examine the possibility that shrinking

Recrudescence of massive fermion production by oscillons

Journal of High Energy Physics, 2017
We bring together the physics of preheating, following a period of inflation, and the dynamics of non-topological solitons, namely oscillons. We show that the oscillating condensate that makes up an oscillon can be an efficient engine for producing heavy

The self-dual classical double copy, and the Eguchi-Hanson instanton

Journal of High Energy Physics, 2019
The double copy is a map from non-abelian gauge theories to gravity, that has been demonstrated both for scattering amplitudes and exact classical solutions.

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.

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.

Generalized virial identities: radial constraints for solitons, instantons, and bounces

Journal of High Energy Physics
We derive a continuous family of virial identities for O(n) symmetric configurations, parameterized by an exponent α that controls the radial weighting.

Domain walls in a non-linear S 2 $$ {\mathbb{S}}^2 $$ -sigma model with homogeneous quartic polynomial potential

Journal of High Energy Physics, 2018
In this paper the domain wall solutions of a Ginzburg-Landau non-linear S 2 $$ {\mathbb{S}}^2 $$ -sigma hybrid model are exactly calculated. There exist two types of basic domain walls and two families of composite domain walls. The domain wall solutions
