Characterizing the post-inflationary reheating history, Part II: Multiple interacting daughter fields
Stefan Antusch, Kenneth Marschall, Francisco Torrenti
We characterize the post-inflationary dynamics of an inflaton coupled to multiple interacting daughter fields () through quadratic-quadratic interactions $…
Characterizing the post-inflationary reheating history, Part I: single daughter field with quadratic-quadratic interaction
Stefan Antusch, Daniel G. Figueroa, Kenneth Marschall +1
We study the evolution of the energy distribution and equation of state of the Universe from the end of inflation until the onset of either radiation domination (RD) or a transient…
Energy distribution and equation of state of the early Universe: matching the end of inflation and the onset of radiation domination
Stefan Antusch, Daniel G. Figueroa, Kenneth Marschall +1
We study the energy distribution and equation of state of the universe between the end of inflation and the onset of radiation domination (RD), considering observationally consiste…
What can we learn from the stochastic gravitational wave background produced by oscillons?
Stefan Antusch, Francesco Cefala, Stefano Orani
The stochastic gravitational wave (GW) background provides a fascinating window to the physics of the very early universe. Beyond the nearly scale-invariant primordial GW spectrum…
Gravitational waves from oscillons after inflation
Stefan Antusch, Francesco Cefala, Stefano Orani
We investigate the production of gravitational waves during preheating after inflation in the common case of field potentials that are asymmetric around the minimum. In particular,…
