Generalized plane waves in Poincaré gauge theory of gravity
arXiv:1708.08766 · doi:10.1103/PhysRevD.96.064031
Abstract
A family of exact vacuum solutions, representing generalized plane waves propagating on the (anti-)de Sitter background, is constructed in the framework of Poincaré gauge theory. The wave dynamics is defined by the general Lagrangian that includes all parity even and parity odd invariants up to the second order in the gauge field strength. The structure of the solution shows that the wave metric significantly depends on the spacetime torsion.
