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…
Causality Violating Solutions in Curvature-Squared Gravity
J. C. R. de Souza, A. F. Santos, R. Bufalo
In this paper, we consider some causality violating solutions in the curvature-squared gravity in order to examine whether closed timelike curves (CTCs) are allowed in these models…
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…
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…
An axially symmetric spacetime with causality violation in Ricci-inverse gravity
J. C. R. de Souza, A. F. Santos
In this paper, Ricci-inverse gravity is investigated. It is an alternative theory of gravity that introduces into the Einstein-Hilbert action an anti-curvature scalar that is obtai…
