Constraints on the baryon density from fast radio bursts using a non-parametric reconstruction of the Hubble parameter
Lázaro L. Sales, Klecio E. L. de Farias, Amilcar R. Queiroz +3
In this study, we use a sample of 130 well-localized fast radio bursts (FRBs) to constrain the physical baryon density , and the astrophysical contribution from host…

Casimir Effect for a Massive Scalar Field in Lorentz-Violating Aether Compactification
K. E. L. de Farias, M. A. Anacleto, A. A. Araújo Filho +4
This work investigates the influence of Lorentz symmetry breaking, introduced by an aether-like field , on the Casimir effect within a five-dimensional flat spacetime. By cons…

Stefan-Boltzmann Law and Thermal Casimir Effect in Neutron Star Spacetime via Thermo Field Dynamics
K. E. L. de Farias, M. A. Anacleto, Rafael A. Batista +5
We investigate the thermal Casimir effect for a massless scalar field in the curved spacetime of a neutron star within the Thermo Field Dynamics (TFD) formalism. Starting from the…
