Gravitational waves in metric-affine gravity theory
Alejandro Jiménez-Cano, Yuri N. Obukhov
We derive the exact gravitational wave solutions in a general class of quadratic metric-affine gauge gravity models. The Lagrangian includes all possible linear and quadratic invar…
Comment on "Einstein-Gauss-Bonnet Gravity in Four-Dimensional Spacetime"
Julio Arrechea, Adrià Delhom, Alejandro Jiménez-Cano
We argue that several statements in Phys. Rev. Lett. 124, 081301 (2020) are not correct.
On the strong coupling of Einsteinian Cubic Gravity and its generalisations
Jose Beltrán Jiménez, Alejandro Jiménez-Cano
In this note we discuss the strong coupling issues inherent to the defining requirement for the so-called Einsteinian Cubic Gravity and its quasi-topological generalisations.
New metric-affine generalizations of gravitational wave geometries
Alejandro Jiménez-Cano
In this paper we explore generalizations of metric structures of the gravitational wave type to geometries containing an independent connection. The aim is simply to establish a ne…
Inconsistencies in four-dimensional Einstein-Gauss-Bonnet gravity
Julio Arrechea, Adrià Delhom, Alejandro Jiménez-Cano
We attempt to clarify several aspects concerning the recently presented four-dimensional Einstein-Gauss-Bonnet gravity. We argue that the limiting procedure outlined in [Phys. Rev.…
General Teleparallel Quadratic Gravity
Jose Beltrán Jiménez, Lavinia Heisenberg, Damianos Iosifidis +2
In this Letter we consider a general quadratic parity-preserving theory for a general flat connection. Imposing a local symmetry under the general linear group singles out the gene…
