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…
Light deflection and gravitational lensing effects inspired by loop quantum gravity
A. R. Soares, C. F. S. Pereira, R. L. L. Vitória +2
In the present work, we theoretically investigate light deflection in the weak and strong field regimes for two regular spacetimes with corrections from loop quantum gravity. We tr…
Holonomy corrected Schwarzschild black hole lensing
A. R. Soares, C. F. S. Pereira, R. L. L. Vitória
In the present work, we theoretically investigate gravitational lensing in the spacetime of a holonomy corrected Schwarzschild black hole. Analytical expressions for the light defl…
Gravitational lensing in a topologically charged Eddington-inspired Born-Infeld spacetime
A. R. Soares, R. L. L. Vitória, C. F. S. Pereira
In the present paper, we study several aspects of gravitational lensing caused by a topologically charged Monopole/Wormhole, both in the weak field limit and in the strong field li…
Strong gravitational lensing in a spacetime with topological charge within the Eddington-inspired Born-Infeld gravity
C. Furtado, J. R. Nascimento, A. Yu. Petrov +2
In this work we calculate the angular deflection of light in the strong field limit in two spacetimes which were previously studied within the Eddington-inspired Born-Infeld gravit…
Gravitational lensing in a black-bounce traversable wormhole spacetime
J. R. Nascimento, A. Yu. Petrov, P. J. Porfirio +1
In this work, we calculate the deflection angle of light in a spacetime that interpolates between regular black holes and traversable wormholes, depending on the free parameter of…
Nonlinear -models in the Eddington-inspired Born-Infeld Gravity
J. R. Nascimento, Gonzalo J. Olmo, P. J. Porfírio +2
In this paper we consider two different nonlinear -models minimally coupled to Eddington-inspired Born-Infeld gravity. We show that the resultant geometries represent minimal mo…
Global Monopole in Palatini f(R) gravity
J. R. Nascimento, Gonzalo J. Olmo, A. Yu. Petrov +2
We consider the space-time metric generated by a global monopole in an extension of General Relativity (GR) of the form . The theory is f…
