Charged black holes in quadratic gravity
Vojtech Pravda, Alena Pravdova, George Turner
We study electrically charged, static, spherically symmetric black holes in quadratic gravity using the conformal-to-Kundt technique, which leads to a considerable simplification o…
Kerr-Schild double copy for Kundt spacetimes of any dimension
Marcello Ortaggio, Vojtech Pravda, Alena Pravdova
We show that vacuum type N Kundt spacetimes in an arbitrary dimension admit a Kerr-Schild (KS) double copy. This is mostly done in a coordinate-independent way using the higher-dim…
Topological black holes in higher derivative gravity
Alena Pravdova, Vojtech Pravda, Marcello Ortaggio
We study static black holes in quadratic gravity with planar and hyperbolic symmetry and non-extremal horizons. We obtain a solution in terms of an infinite power-series expansion…
The Newman-Penrose formalism in quadratic gravity
Robert Svarc, Alena Pravdova, David Miskovsky
The quadratic gravity constraints are reformulated in terms of the Newman-Penrose-like quantities. In such a frame language, the field equations represent a linear algebraic system…
Black holes and other spherical solutions in quadratic gravity with a cosmological constant
Vojtech Pravda, Alena Pravdova, Jiri Podolsky +1
We study static spherically symmetric solutions to the vacuum field equations of quadratic gravity in the presence of a cosmological constant . Motivated by the trace no-hair th…
Black holes and other exact spherical solutions in Quadratic Gravity
Jiri Podolsky, Robert Svarc, Vojtech Pravda +1
We study static, spherically symmetric vacuum solutions to Quadratic Gravity, extending considerably our previous Rapid Communication [Phys. Rev. D 98, 021502(R) (2018)] on this to…
