CosmoLattice 2.0
Jorge Baeza-Ballesteros, Daniel G. Figueroa, Adrien Florio +4
This paper introduces , a major upgrade that substantially broadens the physical scope and computational capabilities of the code…
The art of simulating the early Universe. Part II. Non-canonical cases & gravitational waves
Jorge Baeza-Ballesteros, Daniel G. Figueroa, Adrien Florio +7
We present a discussion on lattice techniques for the simulation of non-canonical field theory circumstances, complementing our previous monograph (arXiv:2006.15122) on canonical c…
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…
The non-linear dynamics of axion inflation: a detailed lattice study
Daniel G. Figueroa, Joanes Lizarraga, Nicolás Loayza +2
We study in detail the fully inhomogeneous non-linear dynamics of axion inflation, identifying three regimes: weak-, mild-, and strong-backreaction, depending on the duration of in…
The strong backreaction regime in axion inflation
Daniel G. Figueroa, Joanes Lizarraga, Ander Urio +1
We study the non-linear dynamics of axion inflation, capturing for the first time the inhomogeneity and full dynamical range during strong backreaction, till the end of inflation.…
Nambu-Goto Dynamics of Field Theory Cosmic String Loops
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Joanes Lizarraga +4
We perform a detailed comparison of the dynamics of cosmic string loops obtained in cosmological field theory simulations with their expected motion according to the Nambu-Goto act…
Loop decay in Abelian-Higgs string networks
Mark Hindmarsh, Joanes Lizarraga, Ander Urio +1
We study the decay of cosmic string loops in the Abelian-Higgs model. We confirm earlier results that loops formed by intersections of infinite strings formed from random-field ini…
