Signatures of primordial energy injection from axion strings

JN Benabou, M Buschmann, S Kumar, Y Park… - Physical Review D, 2024‏ - APS
Axion strings are horizon-size topological defects that may be produced in the early
Universe. Ultralight axion-like particles may form strings that persist to temperatures below …

Extra-dimensional axion expectations

M Reece - arxiv preprint arxiv:2406.08543, 2024‏ - arxiv.org
Axions arising as modes of higher-dimensional gauge fields are known to offer a compelling
solution to the axion quality problem and to naturally arise in string theory. In this context, it is …

Axion mass prediction from adaptive mesh refinement cosmological lattice simulations

JN Benabou, M Buschmann, JW Foster… - arxiv preprint arxiv …, 2024‏ - arxiv.org
The quantum chromodynamics (QCD) axion arises as the pseudo-Goldstone mode of a
spontaneously broken abelian Peccei-Quinn (PQ) symmetry. If the scale of PQ symmetry …

The quality/cosmology tension for a post-inflation QCD axion

Q Lu, M Reece, Z Sun - Journal of High Energy Physics, 2024‏ - Springer
A bstract It is difficult to construct a post-inflation QCD axion model that solves the axion
quality problem (and hence the Strong CP problem) without introducing a cosmological …

Chern-Simmons electrodynamics and torsion dark matter axions

Z Gao, LCG de Andrade - arxiv preprint arxiv:2404.13517, 2024‏ - arxiv.org
In this paper, we delve into the influence of torsion axial pseudo vector on dark photons in
an axion torsionic background, as investigated previously by Duncan et al [Nucl Phys B 387 …

Gravitational waves from the Axiverse

S Das, F Ferrer - arxiv preprint arxiv:2502.12153, 2025‏ - arxiv.org
Models with axion like particles (ALPs) often predict the formation of a string-domain wall
network in the early universe. We study how such networks of defects appear in the context …

Cosmic (super) strings with a time-varying tension

F Revello, G Villa - arxiv preprint arxiv:2411.04186, 2024‏ - arxiv.org
Cosmic (super) strings offer promising ways to test ideas about the early universe and
physics at high energies. While in field theory constructions their tension is usually assumed …

Wormhole-Induced ALP Dark Matter

DY Cheong, K Hamaguchi, Y Kanazawa… - arxiv preprint arxiv …, 2024‏ - arxiv.org
Non-perturbative gravitational effects induce explicit global symmetry breaking terms within
axion models. These exponentially suppressed terms in the potential give a mass …

Axion strings from string axions

JM Cline, C Litos, W Xue - arxiv preprint arxiv:2412.12260, 2024‏ - arxiv.org
A favored scenario for axions to be dark matter is for them to form a cosmic string network
that subsequently decays, allowing for a tight link between the axion mass and relic …

Enhancing precision in electromagnetic force density modulation using LASER control

W Vegt - Journal of Laser Applications, 2025‏ - pubs.aip.org
Einstein's General Relativity framework, founded on spacetime curvature by gravitational
fields and a constant vacuum light speed, faces a new interpretation challenging this …
