Newman-Penrose formalism and exact vacuum solutions to conformal Weyl gravity
Petr Jizba, Kamil Mudruňka
We study the exterior solution for a static, spherically symmetric source in Weyl conformal gravity in terms of the Newman--Penrose formalism. We first show that both the static, u…

Probing Gauss-Bonnet-Corrected Inflation with Gravitational Waves
Kamil Mudrunka, Kazunori Nakayama
The low energy effective action of quantum gravity may include the higher curvature terms such as the Gauss-Bonnet term. The inflaton dynamics may be affected by the Gauss-Bonnet t…
