Gravitational waves in Cubic Metric-Affine Gravity
Sebastian Bahamonde, Jorge Gigante Valcarcel, José M. M. Senovilla
The paper presents exact pp‑wave solutions in a cubic metric‑affine gravity model that include dynamical torsion and nonmetricity, leading to an additional scalar polarization mode…
Black hole superradiance in Poincaré gauge theory
Sebastian Bahamonde, Jorge Gigante Valcarcel
We investigate the phenomenon of black hole superradiance in the presence of torsion within the framework of Poincaré gauge theory. In particular, in contrast to the classical app…
Stability in Cubic Metric-Affine Gravity
Sebastian Bahamonde, Jorge Gigante Valcarcel
We analyse the stability issue of the vector and axial modes of the torsion and nonmetricity tensors around general backgrounds in the framework of cubic Metric-Affine Gravity. We…
Algebraic classification of the gravitational field in general metric-affine geometries
Sebastian Bahamonde, Jorge Gigante Valcarcel, José M. M. Senovilla
We present the algebraic classification of the gravitational field in four-dimensional general metric-affine geometries, thus extending the current results of the literature in the…
