Circular Axion String Loop Simulations: Field Theory and Effective Description
Mathieu Kaltschmidt, Javier Redondo, Ivan Rybak +2
An accurate description of axion strings and their radiation is crucial for understanding their cosmological implications. Motivated by the differing conclusions of previous works,…
Amnesia in the Axion Misalignment Landscape
Kierthika Chathirathas, Cem Eröncel, Mathieu Kaltschmidt +2
Pre-inflationary axion cosmologies admit a broad range of initial velocities and angles that generate a landscape of misalignment histories, whose nonlinear fate and small-scale st…
From Rags to Jeans: Axion Miniclusters from Early matter domination
Ariel Angulo, Paola Arias, Nicolás Bernal +1
In an early matter-dominated era, density and temperature inhomogeneities of the radiation bath grow more efficiently than in the standard radiation-dominated history. If the axion…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
The Spectrum of Global Axion Strings
Mathieu Kaltschmidt, Javier Redondo, Ken'ichi Saikawa +1
The post-inflationary Peccei-Quinn (PQ) symmetry breaking scenario provides a unique opportunity to pinpoint the QCD axion dark matter mass, which is a crucial input for laboratory…
Spectrum of global string networks and the axion dark matter mass
Ken'ichi Saikawa, Javier Redondo, Alejandro Vaquero +1
Cold dark matter axions produced in the post-inflationary Peccei-Quinn symmetry breaking scenario serve as clear targets for their experimental detection, since it is in principle…
Axion minicluster streams in the solar neighbourhood
Ciaran A. J. O'Hare, Giovanni Pierobon, Javier Redondo
A consequence of QCD axion dark matter being born after inflation is the emergence of small-scale substructures known as miniclusters. Although miniclusters merge to form minihalos…
