Scalar Casimir effects in a Lorentz violation scenario induced by the presence of constant vectors
E. R. Bezerra de Mello, M. B. Cruz
In this work, we consider a theoretical model that presents violation of the Lorentz symmetry in the approach of Quantum Field Theory. The theoretical model adopted consists of a r…
Phantom cosmologies from QCD ghost dark energy
Miguel Cruz, Samuel Lepe, Germán E. Soto
We review a dynamical dark energy model scarcely studied in the literature and we introduce two possible generalizations. We discuss separately the behavior of the original model a…
Holography and matter creation revisited
V. H. Cárdenas, Miguel Cruz, Samuel Lepe
The consideration of the holographic dark energy approach and matter creation effects in a single cosmological model is carried out in this work accordingly, we discuss some cases…
Qualitative analysis for viscous cosmologies in a non linear regime of the Israel-Stewart formalism
Gilberto Aguilar-Pérez, Ana A. Avilez-López, Miguel Cruz
We explore the dynamical properties of a cosmological model that includes viscous effects in the dark matter sector of the fluid equations in a flat Friedmann-Lemaitre-Robertson-Wa…
