Non-linear Plane Gravitational Waves as Space-time Defects
F. L. Carneiro, S. C. Ulhoa, J. W. Maluf +1
We consider non-linear plane gravitational waves as propagating space-time defects, and construct the Burgers vector of the waves. In the context of classical continuum systems, th…
Energy-momentum and angular-momentum of a gyratonic pp-waves spacetime
F. L. Carneiro, S. C. Ulhoa, J. F. da Rocha-Neto
Gyratonic plane fronted gravitational waves are exact solutions of Einstein's field equations, which correspond to gravitational waves that carry momentum and angular-momentum. Usi…
Difficulties of Teleparallel Theories of Gravity with Local Lorentz Symmetry
J. W. Maluf, S. C. Ulhoa, J. F. da Rocha-Neto +1
A brief discussion is made about the relevance of surface terms in the Lagrangian and Hamiltonian formulations of theories of gravity. These surface terms play an important role in…
Variations of the Energy of Free Particles in the pp-Wave Spacetimes
J. W. Maluf, J. F. da Rocha-Neto, S. C. Ulhoa +1
We consider the action of exact plane gravitational waves, or pp-waves, on free particles. The analysis is carried out by investigating the variations of the geodesic trajectories…
