On the quantum origin of inflation in the geometric inflation model
Israel Quiros, Roberto De Arcia, Ricardo García-Salcedo +3
In this paper we investigate the cosmological dynamics of geometric inflation by means of the tools of the dynamical systems theory. We focus in the study of two explicit models wh…
Inflationary equilibrium configurations of scalar-tensor theories of gravity
Israel Quiros, Tame Gonzalez, Roberto De Arcia +3
In this paper we investigate the asymptotic dynamics of inflationary cosmological models that are based in scalar-tensor theories of gravity. Our main aim is to explore the global…
Global asymptotic dynamics of Cosmological Einsteinian Cubic Gravity
Israel Quiros, Ricardo García-Salcedo, Tame Gonzalez +2
In this paper we investigate the cosmological dynamics of an up to cubic curvature correction to General Relativity (GR) known as Cosmological Einsteinian Cubic Gravity (CECG), who…
A simple estimation of the size of the molecules using a pencil lead
Ricardo Medel-Esquivel, Isidro Gómez-Vargas, J. Alberto Vázquez +1
The main aim of this article is that students, at the basic level of education, gain a quantitative understanding of the size of molecules by performing a simple experiment easily…
An issue with the classification of the scalar-tensor theories of gravity
Israel Quiros, Roberto De Arcia, Ricardo García-Salcedo +2
In the bibliography a certain confusion arises in what regards to the classification of the gravitational theories into scalar-tensor theories and general relativity with a scalar…
On the phantom barrier crossing and the bounds on the speed of sound in non-minimal derivative coupling theories
Israel Quiros, Tame Gonzalez, Ulises Nucamendi +3
In this paper we investigate the so called "phantom barrier crossing" issue in a cosmological model based in the scalar-tensor theory with non-minimal derivative coupling to the Ei…
Brans-Dicke Galileon and the Variational Principle
Israel Quiros, Ricardo García-Salcedo, Tame Gonzalez +2
This paper is aimed at a (mostly) pedagogical exposition of the derivation of the motion equations of certain modifications of general relativity. Here we derive in all detail the…
The Chameleon Effect in the Jordan Frame of the Brans--Dicke Theory
Israel Quiros, Ricardo García-Salcedo, Tame Gonzalez +1
In this paper we investigate the chameleon effect in the different conformal frames of the Brans--Dicke theory. Given that, in the standard literature on the subject, the chameleon…
Brans--Dicke cosmology does not have the CDM phase as an universal attractor
Ricardo García-Salcedo, Tamé González, Israel Quiros
In this paper we seek for relevant information on the asymptotic cosmological dynamics of the Brans--Dicke theory of gravity for several self-interaction potentials. By means of th…
Introduction to the application of the dynamical systems theory in the study of the dynamics of cosmological models of dark energy
Ricardo García-Salcedo, Tame Gonzalez, Francisco A. Horta-Rangel +2
The theory of the dynamical systems is a very complex subject which has brought several surprises in the recent past in connection with the theory of chaos and fractals. The applic…
Power-Law NLED-Based Magnetic Universe Can Mimic Phantom Behavior
Ricardo García-Salcedo, Tame Gonzalez, Claudia Moreno +1
We study the cosmic dynamics of a magnetic universe supported by non-linear electrodynamics (NLED) Lagrangeans that are proportional to powers of the electromagnetic invariant $\pr…
Randall-Sundrum brane cosmology: modification of late-time cosmic dynamics by exotic matter
Ricardo García-Salcedo, Tame Gonzalez, Claudia Moreno +1
In this paper we show, through the study of concrete examples, that, depending on the cosmic dynamics of the energy density of matter degrees of freedom living in the brane, Randal…
Asymptotic Properties of a Supposedly Regular (Dirac-Born-Infeld) Modification of General Relativity
Ricardo García-Salcedo, Tame Gonzalez, Claudia Moreno +3
We apply the dynamical systems tools to study the asymptotic properties of a cosmological model based on a non-linear modification of General Relativity in which the standard Einst…
