Dereli, T. and Tucker, R. W. (2004) On the energy-momentum density of gravitational plane waves. Classical and Quantum Gravity, 21 (6). pp. 1459-1464. ISSN 1361-6382Full text not available from this repository.
By embedding Einstein's original formulation of general relativity into a broader context, we show that a dynamic covariant description of gravitational stress–energy emerges naturally from a variational principle. A tensor TG is constructed from a contraction of the Bel tensor with a symmetric covariant second degree tensor field Φ and has a form analogous to the stress–energy tensor of the Maxwell field in an arbitrary spacetime. For plane-fronted gravitational waves helicity-2 polarized (graviton) states can be identified carrying non-zero energy and momentum.
