Creation of an inflationary epoch from an Emergent Universe through quantum tunneling
Eduardo I. Guendelman, Ramon Herrera, Pedro Labraña
We consider that the very early Universe was well described by an Emergent Universe, whose geometry was that of a static and classically stable Einstein Universe, which is possible…
Could a thin-shell configuration lie hidden within the Universe?
Mauricio Cataldo, Antonella Cid, Pedro Labraña
This article explores the cosmological scenario in which our Universe contains a hidden thin-shell configuration. We investigate a degenerate modification of the Friedmann-Robertso…
Connecting Early Dark Energy to Late Dark Energy by the Diluting Matter Potential
Eduardo I. Guendelman, Ramon Herrera, Pedro Labrana
In this work we study a scale invariant gravity theory containing two scalar fields, dust particles and a measure defined from degrees of freedom independent of the metric. The int…
Classical and Semiclassical Stability of Emergent Universes in Jordan-Brans-Dicke Theory
Pedro Labraña, Juan Ortiz
The Emergent Universe scenario is based on the assumption that the universe originates from a past-eternal Einstein static (ES) state, subsequently evolving toward an inflationary…
Instant preheating in a scale invariant two measures theory
Eduardo I. Guendelman, Ramon Herrera, Pedro Labrana
The instant preheating mechanism in the framework of a scale invariant two measures theory is studied. We introduce this mechanism into a non oscillating inflationary model as anot…
On the robustness of emptying filling boxes to sudden changes in the wind
John Craske, Graham O. Hughes
We determine the smallest instantaneous increase in the strength of an opposing wind that is necessary to permanently reverse the forward displacement flow that is driven by a two-…
