Holography and matter creation revisited
V. H. Cárdenas, Miguel Cruz, Samuel Lepe
The consideration of the holographic dark energy approach and matter creation effects in a single cosmological model is carried out in this work accordingly, we discuss some cases…
Matter production effects and interacting scenario within a reconstructed mimetic cosmology for late times
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
In this work we explore two possible scenarios that can be considered to extend a recent proposed model by the authors known as reconstructed mimetic cosmology. This study is compl…
Reconstructing Mimetic Cosmology
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +1
We explore the mimetic gravity formulation with the inclusion of a scalar field potential namely, . However, we are not considering any {\it a priori} specific form this term…
Cosmic expansion with matter creation and bulk viscosity
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
We explore the cosmological implications at effective level of matter creation effects in a dissipative fluid for a FLRW geometry; we also perform a statistical analysis for this k…
Challenging matter creation models in the phantom divide
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +2
We perform a study both statistical and theoretical for cosmological models of matter creation and their ability to describe effective phantom models of dark energy. Such models ar…
Stealth's cosmologies
Abigail Alvarez, Cuauhtemoc Campuzano, Víctor Cárdenas +1
We present a novel approach to construct cosmological models endowed with a particular scalar field, the stealth. The model is constructed by studying a scalar field no-minimally c…
Semi-holographic model including the radiation component
Sergio del Campo, Víctor Cárdenas, Juan Magaña +1
In this letter we study the semi holographic model which corresponds to the radiative version of the model proposed by Zhang et al. (Phys. Lett. B 694 (2010), 177) and revisited by…
Chaos and Preheating
Sergio E. Jorás, Victor H. Cárdenas
We show evidence for a relationship between chaos and parametric resonance both in a classical system and in the semiclassical process of particle creation. We apply our considerat…
