The sound of quintessence: analogue Kiselev acoustic black holes
Luis C. N. Santos, H. S. Vieira, Franciele M. da Silva +1
In this work, we demonstrate that the geometry of a spherically symmetric black hole surrounded by a Kiselev anisotropic fluid can be effectively mimicked by an experimental setup…
Black hole solutions surrounded by anisotropic fluid in f(T,T) gravity
Franciele M. da Silva, Luis C. N. Santos, V. B. Bezerra
In this work, we investigate some extensions of the Kiselev black hole solutions in the context of $f(\mathbb{T},\CMcal{T})$ gravity. By mapping the components of the Kiselev energ…
A Bayesian study of quark models in view of recent astrophysical constraints
Franciele M. da Silva, Adamu Issifu, Luiz L. Lopes +2
In this work, we perform a comparative analysis between the density-dependent quark model and the vector MIT bag model using Bayesian analysis. We use the equations of state genera…
Quantum Configuration and Phase Spaces: Finsler and Hamilton Geometries
Saulo Albuquerque, Valdir B. Bezerra, Iarley P. Lobo +5
In this paper, we review two approaches that can describe, in a geometrical way, the kinematics of particles that are affected by Planck-scale departures, named Finsler and Hamilto…
Kiselev black holes in gravity
L. C. N. Santos, F. M. da Silva, C. E. Mota +2
We obtain new exact solutions for the gravitational field equations in the context of gravity, thereby obtaining different classes of black holes surrounded by fluids, tak…
Non-inertial effects on a non-relativistic quantum harmonic oscillator in the presence of a screw dislocation
L. C. N. Santos, F. M. da Silva, C. E. Mota +1
We investigate non-inertial effects induced by a rotating frame on a non-relativistic quantum harmonic oscillator as well as of the topology associated to a screw dislocation, whic…
The extended phase space thermodynamics of Planck-scale-corrected Reissner-Nordström-anti-de Sitter black hole
Iarley P. Lobo, Luis C. N. Santos, V. B. Bezerra +2
We analyze the effect of Planck-scale modified radiation equation of state on the Reissner-Nodström-anti-de Sitter black hole inspired by Kiselev's ansatz. Deformed thermodynamic q…

Luis C. N. Santos, Clésio E. Mota, Franciele M. da Silva +2
Deformed dispersion relations are considered in the study of equations of state of Fermi gas with applications to compact objects. Different choices of deformed energy relations ar…
Generalized Rastall's gravity and its effects on compact objects
Clésio E. Mota, Luis C. N. Santos, Franciele M. da Silva +3
We present a generalization of Rastall's gravity in which the conservation law of the energy-momentum tensor is altered, and as a result, the trace of the energy-momentum tensor is…
Anisotropic Compact Stars in Rastall-Rainbow Gravity
Clésio E. Mota, Luis C. N. Santos, Franciele M. da Silva +3
In this work, we have investigated anisotropic neutron stars in the framework of Rastall-Rainbow gravity. All our calculations were computed using the IU-FSU realistic equation of…

Considering corrections produced by modified dispersion relations on the equation of state parameter of radiation, we study the induced black hole metric inspired by Kiselev's ansa…
Scalar bosons with Coulomb potentials in a cosmic string background: Scattering and bound states
Francisco A. Cruz Neto, Franciele M. da Silva, Luis C. N. Santos +1
