Geometric and Statistical Thermo Field Dynamics in de Sitter Spacetime
D. S. Cabral, L. A. S. Evangelista, J. C. R. de Souza +1
The dynamics of a massive scalar field non-minimally coupled to gravity in an expanding de Sitter universe are investigated. It is shown that a comoving observer identifies the Bun…
Casimir phenomena in bumblebee gravity
D. S. Cabral, A. A. Araújo Filho, A. F. Santos
In this work, we analyze the Casimir effect associated with a massive, non-minimally coupled scalar field in static, spherically symmetric black hole spacetimes arising in bumblebe…
Thermal Bhabha scattering under the influence of non-hermiticity effects
D. S. Cabral, A. F. Santos, R. Bufalo
In this paper, we investigate the Bhabha scattering process within the framework of non-Hermitian QED at finite temperature. In this theory, the hermiticity condition, typically re…
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…
Thermal and Casimir effects in a Lorentz-violating massive scalar field
D. S. Cabral, L. H. A. R. Ferreira, L. A. S. Evangelista +1
In this work, a massive scalar field theory incorporating Lorentz violation is investigated. The symmetry breaking is introduced via a background traceless antisymmetric tensor. Wi…
