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 of…
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…
Lorentz-violating Yukawa theory at finite temperature
D. S. Cabral, L. A. S. Evangelista, J. C. R. de Souza +2
This paper addresses Yukawa theory, focusing on the scattering between two identical fermions mediated by an intermediate scalar boson, considering the effects of thermal contribut…
Exploring the impact of magnetic fields, Lorentz violation and EDM on scattering
D. S. Cabral, A. F. Santos
This paper explores the annihilation process of an electron-positron pair into a heavier lepton-antilepton pair, taking into account the presence of an external classical magnetic…
Time-Machines Construct in and Modified Gravity Theories
F. Ahmed, J. C. R. de Souza, A. F. Santos
In this paper, our objective is to explore a time-machine space-time formulated in general relativity, as introduced by Li (Phys. Rev. D {\bf 59}, 084016 (1999)), within the contex…
Exploring regular black holes within the framework of the TFD formalism
Jhonny A. A. Ruiz, A. F. Santos
In this paper, a massive scalar field non-minimally coupled with gravity is considered. Assuming a regular and spherically symmetric background, specifically a regular black hole s…
Scalar sector of the Myers and Pospelov model: thermal and size effects
L. H. A. R. Ferreira, A. F. Santos, Carlos M. Reyes
The scalar sector of the Myers and Pospelov model is considered. This theory introduces a dimension 5 operator with a preferred four-vector which breaks Lorentz symmetry. We invest…
scattering at finite temperature in the presence of a classical background magnetic field
D. S. Cabral, A. F. Santos
In this work the scattering process is investigated. The cross-section is calculated considering three different effects: temperature, external magnetic…
Cosmological constant Petrov type-N space-time in Ricci-inverse gravity
F. Ahmed, J. C. R. de Souza, A. F. Santos
Our focus is on a specific type-N space-time that exhibits closed time-like curves in general relativity theory within the framework of Ricci-inverse gravity model. The matter-ener…
Thermal Pair Production from Photon-Photon Collision: Breit-Wheeler Process at Finite Temperature
D. S. Cabral, A. F. Santos, R. Bufalo
In this paper we examine the pair production through the Breit-Wheeler process in a thermal background. We compute the thermal contribution to the Breit-Wheeler di…
