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
