AdS Waves as Exact Solutions to Quadratic Gravity
arXiv:1102.1921 · doi:10.1103/PhysRevD.83.084015
Abstract
We give an exact solution of the quadratic gravity in D dimensions. The solution is a plane fronted wave metric with a cosmological constant. This metric solves not only the full quadratic gravity field equations but also the linearized ones which include the linearized equations of the recently found critical gravity. A subset of the solutions change the asymptotic structure of the anti-de Sitter space due to their logarithmic behavior.
