Geodesics and Thermodynamics of a Schwarzschild Black Hole with Hernquist Dark Matter
A. R. P. Moreira, A. Bouzenada, F. M. Belchior +1
In this work, we investigate the physical and geometrical properties of a Schwarzschild black hole (BH) immersed in a Hernquist dark matter halo. To accomplish our purpose, one bui…
Magnetized vortex in three-dimensional gravity
F. C. E. Lima
Modified Gravity Theories (MGTs) are extensions of General Relativity (GR) in its standard formulation. Therefore, within this framework, we will investigate a system composed of a…
Soft breaking of the symmetry in the theory
F. C. E. Lima, C. A. S. Almeida
We consider a two-dimensional scalar field theory that modifies the standard model by introducing a smooth breaking of translational invariance through a hyperbolic generali…
Mitigating the information degradation in a massive Unruh-DeWitt theory
P. H. M. Barros, F. C. E. Lima, C. A. S. Almeida +1
We investigated the influence of the massive scalar field on the information degradation concerning the Unruh-DeWitt (UDW) detectors. In this conjecture, we adopted a system with a…
Kinks and double-kinks in generalized -and -models
F. C. E. Lima, R. Casana, C. A. S. Almeida
Examining the and models within a two-dimensional framework in the flat spacetime and embracing a theory with unconventional kinetic terms, one investigates the e…
