The power spectrum of the circular noise
Daniel Müller
The circular noise is important in connection to Mach's principle, and also as a possible probe of the Unruh effect. In this letter the power spectrum of the detector following the…
Regularized expression for the gravitational energy-momentum in teleparallel gravity and the principle of equivalence
J. W. Maluf, M. V. O. Veiga, J. F. da Rocha-Neto
The expression of the gravitational energy-momentum defined in the context of the teleparallel equivalent of general relativity is extended to an arbitrary set of real-valued tetra…
Contributions from Dilatonic Strings to the Flat Behaviour of the Rotational Curves in Galaxies
M. Leineker Costa, A. L. Naves de Oliveira, M. E. X. Guimaraes
We analyse the flat behaviour of the rotational curves in some galaxies in the framework of a dilatonic, current-carrying string. We determine the expression of the tangential velo…
Information Storage in Black Holes
M. D. Maia
The information loss paradox for Schwarzschild black holes is examined, using the ADS/CFT correspondence extended to the bulk. It is found that the only option compatib…
The gravitational energy-momentum tensor and the gravitational pressure
J. W. Maluf
In the framework of the teleparallel equivalent of general relativity it is possible to establish the energy-momentum tensor of the gravitational field. This tensor has the followi…
Gravitation and Duality Symmetry
V. C. de Andrade, A. L. Barbosa, J. G. Pereira
By generalizing the Hodge dual operator to the case of soldered bundles, and working in the context of the teleparallel equivalent of general relativity, an analysis of the duality…
