Light Deflection due to Spinoptic Effects in Parametrized and Spherically Symmetric Hairy Black Holes
Kelvin S. Alves, Rogerio T. Cavalcanti, Santiago E. Perez Bergliaffa
In the standard geometric optics approximation, null rays propagating in a spherically symmetric black hole background follow planar geodesics. This picture changes, however, when…
Revisiting entropies: formal properties and connections between Boltzmann-Gibbs, Tsallis and Rényi
Kelvin dos Santos Alves, Rogerio Teixeira Cavalcanti
The aim of the present paper is to present a careful and accessible discussion of the formal aspects of Boltzmann-Gibbs and Tsallis entropies. We begin with a brief overview of Bol…
A Covariant Framework for Generalized Spinor Dual Structures
Rodolfo José Bueno Rogerio, Rogerio Teixeira Cavalcanti, Luca Fabbri
In this work, we propose a novel framework for defining the dual structure of a spinor. This construction relies on the basis elements of the Clifford algebra, leading to a covaria…
Hair imprints of the gravitational decoupling and hairy black hole spectroscopy
V. F. Guimarães, R. T. Cavalcanti, R. da Rocha
Hairy black holes by gravitational decoupling (GD) are probed to derive the gravitational waveform produced by perturbation theory applied to these compact objects. Using the Regge…
Deformations in spinor bundles: Lorentz violation and further physical implications
J. M. Hoff da Silva, R. T. Cavalcanti, G. M. Caires da Rocha
This paper delves into the deformation of spinor structures within nontrivial topologies and their physical implications. The deformation is modeled by introducing real functions t…
