The axion mass in the post-inflationary scenario in a minimal scaling model
José Correia, Mark Hindmarsh, Joanes Lizarraga +3
We calculate the dark matter axion mass in the post-inflationary scenario in a minimal model with a set of classical field theory simulations on grids. In the model, th…
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…
Scaling density of axion strings in terasite simulations
José Correia, Mark Hindmarsh, Joanes Lizarraga +3
We report on a study of axion string networks using fixed-grid simulations of up to points per side. The length of string can be characterised in terms of standard dimensio…
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…
Evolution of Semilocal String Networks: II. Velocity estimators
A. Lopez-Eiguren, J. Urrestilla, A. Achúcarro +2
We continue a comprehensive numerical study of semilocal string networks and their cosmological evolution. These can be thought of as hybrid networks comprised of (non-topological)…
Calibrating Analytical Models for Semilocal Strings
A. Lopez-Eiguren
In this work we calibrate two different analytic models of semilocal strings by constraining the values of their free parameters. In order to do so, we use data obtained from the l…
