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…

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…

Unifying Inflation, dark energy and dark matter with a scalar field and exotic fermions
Eduardo Guendelman, Ramon Herrera
In this paper we consider a new approach to unify inflation and the late universe with dark energy and dark matter formulated in a model that includes a non-Riemannian metric indep…
