Gravitomagnetism in Teleparallel Gravity
Abstract The assumption that matter charges and currents could generate fields, which are called, by analogy with electromagnetism, gravitoeletric and gravitomagnetic fields, dates from the origins of General Relativity (GR). On the other hand, the Teleparallel Equivalent of GR (TEGR), as a gauge theory, seems to be the ideal scenario to define these fields, based on the gauge field strength co...
متن کاملSome Remarks on the Coupling Prescription of Teleparallel Gravity
By using a nonholonomic moving frame version of the general covariance principle, an active version of the equivalence principle, an analysis of the gravitational coupling prescription of teleparallel gravity is made. It is shown that the coupling prescription determined by this principle is always equivalent with the corresponding prescription of general relativity, even in the presence of fer...
متن کاملThe Symmetric Teleparallel Gravity
We study symmetric teleparallel (STP) gravity model, in which only spacetime nonmetricity is nonzero. First we obtain STP equivalent Einstein-Hilbert Lagrangian and give an approach for a generic solution in terms of only metric tensor. Then we obtain a spherically symmetric static solution to the Einstein’s equation in STP space-time and discuss the singularities. Finally, we study a model giv...
متن کاملSelected Topics in Teleparallel Gravity
Teleparallel gravity can be seen as a gauge theory for the translation group. As such, its fundamental field is neither the tetrad nor the metric, but a gauge potential assuming values in the Lie algebra of the translation group. This gauge character makes of teleparallel gravity, despite its equivalence to general relativity, a rather peculiar theory. A first important point is that it does no...
متن کاملReissner Nordström Solutions and Energy in Teleparallel Theory
We give three different spherically symmetric spacetimes for the coupled gravitational and electromagnetic fields with charged source in the tetrad theory of gravitation. One of these, contains an arbitrary function and generates the others. These spacetimes give the Reissner Nordström metric black hole. We then, calculated the energy associated with these spacetimes using the superpotential me...
