Tidal fields on braneworlds
Edgard Casal de Rey Neto
We write out the geodesic deviations that take place in a dimensional brane world subspace of a higher dimensional spacetime by splitting out the brane and the extra spac…
Braneworld with Induced Axial Symmetry
Edgard Casal de Rey Neto
We take arbitrary gravitational perturbations of a 5d spacetime and reduce it to the form an axially symmetric warped braneworld. Then, we write the filed equations for the lineari…
Wave polarizations for a beam-like gravitational wave in quadratic curvature gravity
E. C. de Rey Neto, J. C. N. de Araujo, O. D. Aguiar
We compute analytically the tidal field and polarizations of an exact gravitational wave generated by a cylindrical beam of null matter of finite width and length in quadratic curv…
Geodesic deviation in pp-wave spacetimes of quadratic curvature gravity
Edgard C. de Rey Neto
We write the equation of geodesic deviations in the spacetime of -waves in terms of the Newman-Penrose scalars and apply it to study gravitational waves in quadratic curvature…
