Black Holes Surrounded by Perfect Fluid Dark Matter in Eddington-inspired Born-Infeld Gravity
A. R. Soares, C. F. S. Pereira, R. L. L. Vitória
In this work, we exactly derive the solution for the gravitational field of a black hole in Eddington-inspired Born-Infeld (EiBI) gravity, surrounded by perfect fluid dark matter.…
Numerical study of non-relativistic quantum systems and small oscillations induced in a helically twisted geometry
C. F. S. Pereira, R. L. L. Vitória, A. R. Soares +3
We investigate bound states of a non-relativistic scalar particle in a three-dimensional helically twisted (torsional) geometry, considering both the free case and the presence of…
Light deflection and gravitational lensing effects in acoustic black-bounce spacetime
C. F. S. Pereira, A. R. Soares, M. V. de S. Silva +2
In the present work, we analyze the gravitational deflection for a light beam in the weak and strong field regimes for the gravitational analogue geometry of an acoustic black hole…
Rotation effect for chiral magnetic cosmic string in the Kaluza-Klein theory
Ricardo L. L. Vitória, Carlos F. S. Pereira, Érico V. B. Leite +2
We have investigated bound state solutions for a scalar particle described in the spacetime of a chiral cosmic string subjected to rotational effects in a Kaluza-Klein theory. We s…
On the Klein-Gordon oscillators in Eddington-inspired Born-Infeld gravity global monopole spacetime and a Wu-Yang magnetic monopole
Omar Mustafa, Adriano R. Soares, Carlos F. S. Pereira +1
We consider Klein-Gordon (KG) particles in a global monopole (GM) spacetime within Eddington-inspired Born-Infeld gravity (EiBI-gravity) and in a Wu-Yang magnetic monopole (WYMM).…
Relativistic quantum oscillators in the global monopole spacetime
E. A. F. Bragança, R. L. L. Vitória, H. Belich +1
We investigated the effects of the global monopole spacetime on the Dirac and Klein-Gordon relativistic quantum oscillators. In order to do this, we solve the Dirac and Klein-Gordo…
A massive scalar field under the effects of the Lorentz symmetry violation by a CPT-odd non-minimal coupling
Ricardo L. L. Vitória, Humberto Belich
In this paper, based on the Standard Model Extended gauge sector, we made a non-minimal coupling in the Klein-Gordon equation which characterizes the Lorentz symmetry violation and…
A central potential with a massive scalar field in a Lorentz symmetry violation environment
Ricardo L. L. Vitória, Humberto Belich
We investigate the behaviour of a massive scalar field under the influence of a Coulomb-type and central linear central potentials inserted in the Klein-Gordon equation by modifyin…
On a relativistic scalar particle subject to the Klein-Gordon oscillator, the Coulomb potential and a linear scalar potential
R. L. L. Vitória, C. Furtado, K. Bakke
The relativistic quantum dynamics of an electrically charged particle subject to the Klein-Gordon oscillator and the Coulomb potential is investigated. By searching for relativisti…
