Nonlocal Rarita-Schwinger theory
Fernando M. Belchior, Roberto V. Maluf
In this paper, one constructs a nonlocal extension of the Rarita-Schwinger theory for spin- fermions. Two classes of analytic form factors are considered: scalar form factors…
Duality in topologically massive models with term
Fernando M. Belchior, Roberto V. Maluf
This paper aims to investigate the classical duality between the -Maxwell-Kalb-Ramond (MKR) theory and a self-dual non-gauge-invariant model. First, we establish the equiva…
Braneworlds in Einstein-Scalar-Gauss-Bonnet gravity
José Euclides G. Silva, Leandro A. Lessa, Roberto V. Maluf
We explore the features of a thick braneworld model in five dimensions governed by a Einstein-Gauss-Bonnet gravity with a non-minimal coupling to a dynamical scalar field. We consi…
Fermionic greybody factors and strong gravitational lensing by Lorentz-violating global monopole
F. M. Belchior, R. V. Maluf, A. R. M. Oliveira +2
In this work, we study the greybody factors (GFs) of spin 1/2 and spin 3/2 fermions for a black hole with global monopole in self-interacting Kalb-Ramond gravity with Lorentz symme…
Echoes and quasinormal modes of asymmetric black bounces
Alana C. L. Santos, Leandro A. Lessa, Roberto V. Maluf +1
We study quasinormal modes and echoes of symmetric and asymmetric black bounce solutions generated by anisotropic fluids within the framework of general relativity. We derive the e…
Regular black hole solutions in -dimensional gravity coupled to nonlinear electrodynamics
Miguel A. S. Pinto, Roberto V. Maluf, Gonzalo J. Olmo
In this paper, we investigate regular black hole solutions in the (2+1)-dimensional versions of General Relativity and gravity, both coupled to nonlinear electrodynamics.…
