Modified gravity with disappearing cosmological constant
L. N. Granda
New corrections to General Relativity are considered in the context of modified gravity, that satisfy cosmological and local gravity constraints. The proposed models behave…
CDM without cosmological constant
L. N. Granda
A type of exponential correction to General Relativity gives viable modified gravity model of dark energy. The model behaves as at large curvature where an effective cosmolo…
Modified gravity with an exponential function of curvature
L. N. Granda
The role of an exponential function of the scalar curvature in the modified gravity is analyzed. Two models are proposed. A toy model that complies with local and cosmological cons…
Higgs inflation with non-minimal derivative coupling to gravity
L. N. Granda, D. F. Jimenez, W. Cardona
We consider an extension of Higgs inflation in which the Higgs field is non-minimally coupled to gravity through its kinetic term. We analyzed power-law coupling functions with pos…
Higgs Inflation with linear and quadratic curvature corrections
L. N. Granda, D. F. Jimenez
We consider a single scalar field inflation model with Higgs potential and curvature corrections given by non-minimal derivative coupling to gravity and coupling to the Gauss-Bonne…
Modified Gravity in the framework of holographic dark energy
L. N. Granda, G. D. Rojas
The modified gravity is considered in the framework of the holographic dark energy. An analysis of the autonomous system, the critical points and their stability is presented. Unli…
