Note on the equation of state of geometric dark-energy in f(R) gravity
Luisa G. Jaime, Leonardo Patiño, Marcelo Salgado
We focus on the analysis of three inequivalent equations of state of geometric dark energy in cosmology that have been considered in the past and discuss their differences,…
About matter and dark-energy domination eras in R^n gravity or lack thereof
Luisa G. Jaime, Leonardo Patiño, Marcelo Salgado
We provide further numerical evidence which shows that R^n models in f(R) metric gravity whether produces a late time acceleration in the Universe or a matter domination era (usual…
Cosmology in f(R) exponential gravity
Luisa Jaime, Marcelo Salgado, Leonardo Patino
Using an approach that treats the Ricci scalar itself as a degree of freedom, we analyze the cosmological evolution within an f(R) model that has been proposed recently (exponentia…
f(R) Cosmology revisited
Luisa G. Jaime, Leonardo Patino, Marcelo Salgado
We consider a class of metric f(R) modified gravity theories, analyze them in the context of a Friedmann-Robertson-Walker cosmology and confront the results with some of the known…
Robust approach to f(R) gravity
Luisa G. Jaime, Leonardo Patino, Marcelo Salgado
We consider metric f(R) theories of gravity without mapping them to their scalar-tensor counterpart, but using the Ricci scalar itself as an "extra" degree of freedom. This approac…
The field-to-particle transition problem
Jeronimo Cortez, Leonardo Patino, Hernando Quevedo
We formulate in an intuitive manner several conceptual aspects of the field-to-particle transition problem which intends to extract physical properties of elementary particles from…
