Reconstructing Mimetic Cosmology
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +1
We explore the mimetic gravity formulation with the inclusion of a scalar field potential namely, . However, we are not considering any {\it a priori} specific form this term…
Cosmic expansion with matter creation and bulk viscosity
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
We explore the cosmological implications at effective level of matter creation effects in a dissipative fluid for a FLRW geometry; we also perform a statistical analysis for this k…
Non-zero torsion and late cosmology
Miguel Cruz, Fernando Izaurieta, Samuel Lepe
In this work, we study some thermodynamical aspects associated with torsion in a flat FLRW spacetime cosmic evolution. By implementing two Ansatze for the torsion term, we find tha…
Casimir energy and topological mass for a massive scalar field with Lorentz violation
M. B. Cruz, E. R. Bezerra de Mello, H. F. Santana Mota
A Lorentz symmetry violation aether-type theoretical model is considered to investigate the Casimir effect and the generation of topological mass associated with a self-interacting…
Polar gravitational perturbations and quasinormal modes of a loop quantum gravity black hole
M. B. Cruz, F. A. Brito, C. A. S. Silva
In this work, we have calculated the polar gravitational quasinormal modes for a quantum corrected black hole model, that arises in the context of Loop Quantum Gravity, known as Se…
Challenging matter creation models in the phantom divide
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +2
We perform a study both statistical and theoretical for cosmological models of matter creation and their ability to describe effective phantom models of dark energy. Such models ar…
