Cosmic evolution from Lorentz-violating bumblebee dynamics and Tsallis holographic dark energy
E. M. Siquieri, D. S. Cabral, A. F. Santos
In this work, the behavior, evolution, and expansion of the universe are investigated within a Lorentz-violating framework driven by Tsallis holographic dark energy. The cosmologic…
Gödel-type universes in unimodular gravity
R. Raimarda, A. F. Santos, R. Bufalo
In this paper, the Gödel-type universes are examined within the framework of unimodular gravity. Since the existence of Gödel solutions is intrinsically related to the presence o…
Non-Hermitian electron-positron annihilation under thermal effects
D. S. Cabral, A. F. Santos, R. Bufalo +1
In this paper we examine the thermal effects into the scattering in a non-hermitian extension of QED. We compute the thermal contributions to this…
Barrow holographic dark energy: a path to reconstructing gravity
P. S. Ens, A. F. Santos
In this paper, we investigate one of the established methods for reconstructing modified gravity models from a dark energy model, with the aim of discovering relationships between…
