Evolving Lorentzian wormholes supported by phantom matter with constant state parameters
Mauricio Cataldo, Pedro Labrana, Sergio del Campo +2
In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made out of phantom energy. We show that this exotic source can support the existence of…
Open Inflationary Universes in Gauss-Bonnet Brane Cosmology
Sergio del Campo, Ramon Herrera, Joel Saavedra
In this article, we study a type of one-field approach for open inflationary universe scenario in the context of braneworld models with a Gauss-Bonnet correction term. For a one-bu…
Warm inflation in the DGP brane-world model
Sergio del Campo, Ramon Herrera
Warm inflationary universe models on a warped Dvali-Gabadadze-Porrati brane are studied. General conditions required for these models to be realizable are derived and discussed. By…
Tachyonic open inflationary universes
Leonardo Balart, Sergio del Campo, Ramon Herrera +2
We study one-field open inflationary models in a universe dominated by tachyon matter. In these scenarios, we determine and characterize the existence of the Coleman-De Lucia (CDL)…
