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…
Ricci Reheating on the Lattice
Daniel G. Figueroa, Toby Opferkuch, Ben A. Stefanek
We study the dynamics of a non-minimally coupled (NMC) scalar spectator field in non-oscillatory inflationary scenarios, where there is a transition from inflation to kination domi…
Gravitational Waves from an Axion-Dark Photon System: A Lattice Study
Wolfram Ratzinger, Pedro Schwaller, Ben A. Stefanek
In this work, we present a lattice study of an axion - dark photon system in the early Universe and show that the stochastic gravitational wave (GW) background produced by this sys…
