Gravitational waves with torsion in 3D
arXiv:1406.2850 · doi:10.1103/PhysRevD.90.044006
Abstract
We study gravitational waves with torsion as exact vacuum solutions of three-dimensional gravity with propagating torsion. The new solutions are a natural generalization of the plane-fronted gravitational waves in general relativity with a cosmological constant, in the presence of matter.
