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…
Properties of oscillons in hilltop potentials: energies, shapes, and lifetimes
Stefan Antusch, Francesco Cefala, Francisco Torrenti
Oscillons are spatially localised strong fluctuations of a scalar field. They can e.g. form after inflation when the scalar field potential is shallower than quadratic away from th…
Adiabatic regularization with a Yukawa interaction
Antonio Ferreiro, Adrian del Rio, Jose Navarro-Salas +2
We extend the adiabatic regularization method for an expanding universe to include the Yukawa interaction between a quantized Dirac field and a homogeneous time-dependent scalar fi…
Gravitational wave production from preheating: parameter dependence
Daniel G. Figueroa, Francisco Torrenti
Parametric resonance is among the most efficient phenomena generating gravitational waves (GWs) in the early Universe. The dynamics of parametric resonance, and hence of the GWs, d…
