The spectrum of axions in a scaling string network
José Correia, Mark Hindmarsh, Joanes Lizarraga +3
We report on measurements of axion spectra and their unequal time correlators in simulations on fixed-grids, the largest such measurements to date. We use a novel combina…
Kinetic Fragmentation of the QCD Axion on the Lattice
Matteo Fasiello, Joanes Lizarraga, Alexandros Papageorgiou +1
Kinetic misalignment, one of the most compelling scenarios for the non-thermal generation of axion dark matter, is generally accompanied by axion fragmentation, a process in which…
Comparative study of the strong backreaction regime in axion inflation: the effect of the potential
Joanes Lizarraga, Carmelo López-Mediavilla, Ander Urio
Recent works have demonstrated the necessity of capturing the local inhomogeneous physics in axion inflation, and showed new genuine features, most notably the extension of the inf…
