The generalized second law in the emergent universe
Sergio del Campo, Ramon Herrera, Diego Pavon
This paper studies whether the generalized second law of thermodynamics is fulfilled in the transition from a generic initial Einstein static phase to the inflationary phase, with…
Warm-Intermediate inflationary universe model in braneworld cosmologies
Ramon Herrera, Eugenio San Martin
Warm-intermediate inflationary universe models in the context of braneworld cosmologies, are studied. This study is done in the weak and strong dissipative regimes. We find that, t…
Emergent Universe from Scale Invariant Two Measures Theory
Sergio del Campo, Eduardo I. Guendelman, Alexander B. Kaganovich +2
The dilaton-gravity sector of a linear in the scalar curvature, scale invariant Two Measures Field Theory (TMT), is explored in detail in the context of closed FRW cosmology and sh…
diagnostics on the nature of dark energy
Sergio del Campo, Ramon Herrera, Diego Pavon
The two dominant components of the cosmic budget today, pressureles matter and dark energy, may or may not be interacting with each other. Currently, both possibilities appear comp…
On holographic dark-energy models
Sergio del Campo, Júlio. C. Fabris, Ramón Herrera +1
Different holographic dark-energy models are studied from a unifying point of view. We compare models for which the Hubble scale, the future event horizon or a quantity proportiona…
