On Thermodynamics of Kerr Black Hole
S. C. Ulhoa, A. F. Santos, E. P. Spaniol +1
The gravitational Stefan-Boltzmann law is considered for the Kerr black hole in the weak-field limit. The energy-momentum tensor predicted by Teleparallelism Equivalent to General…
On Gravitational Stefan-Boltzmann Law and Casimir Effect in FRW Universe
A. F. Santos, S. C. Ulhoa, E. P. Spaniol +1
Both Stefan-Boltzmann law and the Casimir effect, in a universe described by the FRW metric with zero curvature, are calculated. These effects are described by Thermo Field Dynamic…
On Regular Black Holes at Finite Temperature
S. C. Ulhoa, E. P. Spaniol, R. Gomes +2
The Thermo Field Dynamics (TFD) formalism is used to investigate the regular black holes at finite temperature. Using the Teleparalelism Equivalent to General Relativity (TEGR) the…
On Quantization of a Slow Rotating Kerr Black Hole
S. C. Ulhoa, E. P. Spaniol, R. G. G. Amorim
In this article we calculate the total angular momentum for Kerr space-time for slow rotations. In order to analyze the role of such quantity we apply Weyl quantization method to o…
On Gravitational Entropy of de Sitter Universe
S. C. Ulhoa, E. P. Spaniol
The paper deals with the calculation of the gravitational entropy in the context of teleparallel gravity for de Sitter space-time. In such a theory it is possible to define gravita…
On the Gravitational Energy-Momentum Vector in f(T) Theories
S. C. Ulhoa, E. P. Spaniol
This work is devoted to analyze the energy of the Universe in the context of f(T) theories. Such theories are the analogous counterpart of the well known f(R) theories that, howeve…
The role of observers in the measurement of the Teleparallel Gravitoelectromagnetic fields in different geometries
Ednardo P. Spaniol, Leandro R. A. Belo, Juliano A. de Deus +1
In the context of the Teleparallel Equivalent of General Relativity (TEGR) we have investigated the role of local observers, associated with tetrad fields, in description of the gr…
Kinematics of the internal space associated with the TEGR
Leandro R. A. Belo, Ednardo P. Spaniol, Juliano A. de Deus +1
In the context of Teleparallel Equivalent of General Relativity - TEGR - we have obtained, through the second kind gauge transformations, the most fundamental transformations, name…
A look on the internal structure of Teleparallel Equivalent of General Relativity
L. R. A. Belo, E. P. Spaniol, J. A. de Deus +1
Using the Dirac procedure to treat constraints dynamical sistems applied to gravitation, as described in the context of Teleparallel Equivalent of General Relativity (TEGR), we inv…
Gravitomagnetism in teleparallel gravity
E. P. Spaniol, V. C. de Andrade
The assumption that matter charges and currents could generate fields, which are called, by analogy with electromagnetism, gravitoeletric and gravitomagnetic fields, dates from the…
