The Role of Vectors in Reheating
Marcos A. G. Garcia, Kunio Kaneta, Wenqi Ke +3
We explore various aspects concerning the role of vector bosons during the reheating process. Generally, reheating occurs during the period of oscillations of the inflaton condensa…
Effects of Fragmentation on Post-Inflationary Reheating
Marcos A. G. Garcia, Mathieu Gross, Yann Mambrini +3
We consider the effects of fragmentation on the post-inflationary epoch of reheating. In simple single field models of inflation, an inflaton condensate undergoes an oscillatory ph…
Reheating constraints and consistency relations of the Starobinsky model and some of its generalizations
Marcos A. G. Garcia, Gabriel Germán, R. Gonzalez Quaglia +1
Building on the success of the Starobinsky model in describing the inflationary period of the universe, we investigate two simple generalizations of this model and their constraint…
Reheating after Inflaton Fragmentation
Marcos A. G. Garcia, Mathias Pierre
In the presence of self-interactions, the post-inflationary evolution of the inflaton field is driven into the non-linear regime by the resonant growth of its fluctuations. The onc…
A New Window into Gravitationally Produced Scalar Dark Matter
Marcos A. G. Garcia, Mathias Pierre, Sarunas Verner
Conventional scenarios of purely gravitationally produced dark matter with masses below the Hubble parameter at the end of inflation are in tension with Cosmic Microwave Background…
Isocurvature Constraints on Scalar Dark Matter Production from the Inflaton
Marcos A. G. Garcia, Mathias Pierre, Sarunas Verner
We investigate the production of a spectator scalar dark matter field that is directly coupled to the inflaton during inflation and reheating. We consider two specific inflationary…
