On Nanocones as a Gravitational Analog System
F. L. Carneiro, B. C. C. Carneiro, D. L. Azevedo +1
This study delves into the fundamental properties of graphene and boron nitride (BN) nanostructures, exploring their torsional energy characteristics within the framework of Telepa…
On Reference Frames and Coordinate Transformations
F. L. Carneiro, S. C. Ulhoa, M. P. Lobo
This article explores the differences between frame and coordinate transformations in relativistic theories. We highlight the key role of tetrad fields in connecting spacetime and…
The irreducible mass of a regular rotating black hole
F. L. Carneiro, S. C. Ulhoa, J. F. da Rocha-Neto +1
This article presents an analysis of regular rotating black hole solutions within the framework of Teleparallel Equivalent to General Relativity (TEGR). The study evaluates the tot…
Lower tensor-to-scalar ratio as possible signature of modified gravity
Abraão J. S. Capistrano, Rafael C. Nunes, Luís A. Cabral
This paper simplifies the induced four-dimensional gravitational equations originating from a five-dimensional bulk within the framework of Nash's embeddings, incorporating them in…
Tetrad Fields, Reference Frames, and the Gravitational Energy-Momentum in the Teleparallel Equivalent of General Relativity
J. W. Maluf, F. L. Carneiro, S. C. Ulhoa +1
We review the concept and definitions of the energy-momentum and angular momentum of the gravitational field in the teleparallel equivalent of general relativity (TEGR). The import…
Kerr-Schild Tetrads and the Nijenhuis Tensor
J. W. Maluf, F. L. Carneiro, S. C. Ulhoa +1
We write the Kerr-Schild tetrads in terms of the flat space-time tetrads and of a (1,1) tensor . This tensor can be considered as a projection operator, since it transforms…
On the Black Hole Acceleration in the C-metric Space-time
F. L. Carneiro, S. C. Ulhoa, J. W. Maluf
We consider the C-metric as a gravitational field configuration that describes an accelerating black hole in the presence of a semi-infinite cosmic string, along the accelerating d…
