The Work-Energy Relation for Particles on Geodesics in the pp-Wave Spacetimes
J. W. Maluf, J. F. da Rocha-Neto, S. C. Ulhoa +1
A non-linear gravitational wave imparts gravitational acceleration to all particles that are hit by the wave. We evaluate this acceleration for particles in the pp-wave space-times…
Plane Gravitational Waves, the Kinetic Energy of Free Particles and the Memory Effect
J. W. Maluf, J. F. da Rocha-Neto, S. C. Ulhoa +1
It is shown that in the passage of a short burst of non-linear plane gravitational wave, the kinetic energy of free particles may either decrease or increase. The decreasing or inc…
Bondi-Sachs energy-momentum and the energy of gravitational radiation
J. W. Maluf, J. F. da Rocha Neto, S. C. Ulhoa
We construct the gravitational energy-momentum of the Bondi-Sachs space-time, in the famework of the teleparallel equivalent of general relativity (TEGR). The Bondi-Sachs line elem…
Gravitational Pressure and the Accelerating Universe
K. H. C. Castello-Branco, J. F. da Rocha-Neto
In the context of the Teleparallel Equivalent of General Relativity (TEGR) one can obtain an alternative insight into General Relativity, as has been shown in addressing properties…
Gravitational waves and the breaking of parallelograms in space-time
J. W. Maluf, S. C. Ulhoa, J. F. da Rocha-Neto
We show that plane-fronted gravitational waves induce the breaking of parallelograms in space-time, in the context of the teleparallel equivalent of general relativity (TEGR). The…
The angular momentum of the gravitational field and the Poincare group
J. W. Maluf, S. C. Ulhoa, F. F. Faria +1
We redefine the gravitational angular momentum in the framework of the teleparallel equivalent of general relativity. In similarity to the gravitational energy-momentum, the new de…
