Higher-order gravity models: corrections up to cubic curvature invariants and inflation
C. M. G. R. Morais, G. Rodrigues-da-Silva, L. G. Medeiros
We construct a higher-order gravity model including all corrections up to mass dimension six. Starting from the Jordan frame, we derive the field equations and specialize to the FL…
Second-order corrections to Starobinsky inflation
G. Rodrigues-da-Silva, L. G. Medeiros
Higher-order theories of gravity are extensions to general relativity (GR) motivated mainly by high-energy physics searching for GR ultraviolet completeness. They are characterized…
Higher-order extension of Starobinsky inflation: initial conditions, slow-roll regime, and reheating phase
G. Rodrigues-da-Silva, J. Bezerra-Sobrinho, L. G. Medeiros
The most current observational data corroborate the Starobinsky model as one of the strongest candidates in the description of an inflationary regime. Motivated by such success, ex…
Spherically Symmetric Solutions in Higher-Derivative Theories of Gravity
G. Rodrigues-da-Silva, L. G. Medeiros
Higher-order theories of gravity have received much attention from several areas including quantum gravity, string theory and cosmology. This paper proposes a higher-order gravity…
