Comment on "More Axions from Strings''
Mark Hindmarsh, Joanes Lizarraga, Asier Lopez-Eiguren +1
We comment on a claim that axion strings show a long-term logarithmic increase in the number of Hubble lengths per Hubble volume [arXiv:2007.04990], thereby violating the standard…
Hubble-induced phase transitions on the lattice with applications to Ricci reheating
Dario Bettoni, Asier Lopez-Eiguren, Javier Rubio
Using 3+1 classical lattice simulations, we follow the symmetry breaking pattern and subsequent non-linear evolution of a spectator field non-minimally coupled to gravity when the…
Approach to scaling in axion string networks
Mark Hindmarsh, Joanes Lizarraga, Asier Lopez-Eiguren +1
We study the approach to scaling in axion string networks in the radiation era, through measuring the root-mean-square velocity as well as the scaled mean string separation …
