Stacking a 4D geometry into an Einstein-Gauss-Bonnet bulk
Carlos Barcelo, Roy Maartens, Carlos F. Sopuerta +1
In Einstein gravity there is a simple procedure to build D-dimensional spacetimes starting from (D-1)-dimensional ones, by stacking any (D-1)-dimensional Ricci-flat metric into the…
Preheating - cosmic magnetic dynamo ?
Bruce A. Bassett, Giuseppe Pollifrone, Shinji Tsujikawa +1
We study the amplification of large-scale magnetic fields during preheating and inflation in several different models. Preheating can resonantly amplify seed fields on cosmological…
Multi-field fermionic preheating
Shinji Tsujikawa, Bruce A. Bassett, Fermin Viniegra
Fermion creation during preheating in the presence of multiple scalar fields exhibits a range of interesting behaviour relevant to estimating post-inflation gravitino abundances. W…
