δ Gravity: Dark Sector, Post-Newtonian Limit and Schwarzschild Solution
(2019)
We present a new kind of model, which we call Theories, where standard theories are modified including new fields, motivated by an additional symmetry ( symmetry). In previous works, we proved that Theories just ...

Gravity Equation and Trade Agreements: A Different Econometric Approach

An Accelerating Universe without Lambda: Delta Gravity Using Monte Carlo
(2019)
A gravitational field model based on two symmetric tensors, gμν and g˜μν , is studied, using a Markov Chain Monte Carlo (MCMC) analysis with the most updated catalog of SN-Ia. In this model, new matter fields are added to ...
Quantum gravity and the holographic dark energy cosmology
(2016-04-01)
The holographic dark energy model is obtained from a cosmological constant generated by generic quantum gravity effects giving a minimum length. By contrast, the usual bound for the energy density to be limited by the ...
Smooth braneworld models possibility in modified gravities
(World Scientific Publ Co Pte Ltd, 2015-10-01)
In this paper, it is shown that the consideration of the braneworld consistency conditions within the framework of bulk modified gravities allows for the existence of thick branes in the five-dimensional case with compact ...
An analog model for quantum lightcone fluctuations in nonlinear optics
(2013-02-01)
We propose an analog model for quantum gravity effects using nonlinear dielectrics. Fluctuations of the spacetime lightcone are expected in quantum gravity, leading to variations in the flight times of pulses. This effect ...
Quest for the extra degree of freedom in f ( T ) gravity
(American Physical Society, 2018-12)
It has recently been shown that f(T) gravity has n(n−3)/2+1 physical degrees of freedom (d.o.f.) in n dimensions, contrary to previous claims. The simplest physical interpretation of this fact is that the theory possesses ...
