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…
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…
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…
