Numerical simulations of magnetic monopole evolution in an expanding universe
Mark Hindmarsh, Asier Lopez-Eiguren, Riikka Seppä +1
Magnetic monopoles are an inevitable feature of post-inflation symmetry-breaking phase transitions in grand unified theories. Analytic estimates of their density indicate that they…
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…
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 …
Cosmological Evolution of Semilocal String Networks
A. Achucarro, A. Avgoustidis, A. Lopez-Eiguren +2
Semilocal strings -- a particular limit of electroweak strings -- are an interesting example of a stable non-topological defect whose properties resemble those of their topological…
The scaling density of axion strings
Mark Hindmarsh, Joanes Lizarraga, Asier Lopez-Eiguren +1
In the QCD axion dark matter scenario with post-inflationary Peccei-Quinn symmetry breaking, the number density of axions, and hence the dark matter density, depends on the length…
Scaling in necklaces of monopoles and semipoles
Mark Hindmarsh, Anna Kormu, Asier Lopez-Eiguren +1
Models of symmetry breaking in the early universe can produce networks of cosmic strings threading 't Hooft-Polyakov monopoles. In certain cases there is a larger global symmetry g…
