Geometric Cosmology models: statistical analysis with observational data
Matías Leizerovich, Luisa G. Jaime, Susana J. Landau +1
Although the standard cosmological model is capable of explaining most current observational data, it faces some theoretical and observational issues. This is the main motivation f…
On Geometric Cosmology
Gustavo Arciniega, Luisa G. Jaime, Susana J. Landau +1
We present a modification to General Relativity by making a redefinition of the coupling constant in front of the Ricci curvature scalar along with the Generalized Quasi-topologica…
A unified geometric description of the Universe: from inflation to late-time acceleration without an inflaton nor a cosmological constant
Luisa G. Jaime, Gustavo Arciniega
We present a cosmological model arising from a gravitational theory with an infinite tower of higher-order curvature invariants that can reproduce the entire evolution of the Unive…
Implementation of two-field inflation for cosmic linear anisotropy solving system
Braulio Morales-Martínez, Gustavo Arciniega, Luisa G. Jaime +1
We outline the modifications in the numerical Boltzmann code Cosmic Linear Anisotropy Solving System (CLASS) in order to include extra inflationary fields. The functioning of the c…
A single parameterization for dark energy and modified gravity models
Mariana Jaber, Gustavo Arciniega, Luisa G. Jaime +1
Perhaps the most explored hypothesis for the accelerated cosmic expansion rate arises in the context of extra fields or modifications to General Relativity. A prevalent approach is…
Inflationary predictions of Geometric Inflation
Gustavo Arciniega, Luisa Jaime, Gabriella Piccinelli
In the framework of gravitational models obtained from the Geometric Inflation's proposal, where an infinite tower of curvature scalars are included into the action, we compute the…
Geometric Inflation
Gustavo Arciniega, Pablo Bueno, Pablo A. Cano +3
We argue that the presence of an inflationary epoch is a natural, almost unavoidable, consequence of the existence of a sensible effective action involving an infinite tower of hig…
Towards geometric inflation: the cubic case
Gustavo Arciniega, Jose D. Edelstein, Luisa G. Jaime
We present an up to cubic curvature correction to General Relativity with the following features: (i) its vacuum spectrum solely consists of a graviton and is ghost-free, (ii) it p…
Geometric description of the thermodynamics of a black hole with power Maxwell invariant source
Gustavo Arciniega, Alberto Sánchez
Considering a nonlinear charged black hole as a thermodynamics system, we study the geometric description of its phase transitions. Using the formalism of geometrothermodynamics we…
Brighter Branes, enhancement of photon production by strong magnetic fields in the gauge/gravity correspondence
Gustavo Arciniega, Francisco Nettel, Patricia Ortega +1
We use the gauge/gravity correspondence to calculate the rate of photon production in a strongly coupled N=4 plasma in the presence of an intense magnetic field. We start by constr…
Topological quantization of the free massive bosonic field
Gustavo Arciniega, Francisco Nettel, Leonardo Patiño +1
We present a topological quantization of free massive bosonic fields as the first example of a classical field theory with a quantum counterpart to be studied under this formalism.…
Topological discretization of bosonic strings
Gustavo Arciniega, Francisco Nettel, Leonardo Patiño +1
We apply the method of topological quantization to obtain the bosonic string topological spectrum propagating on a flat background. We define the classical configuration of the sys…
