Quasinormal modes of Schwarzschild black holes in projective invariant Chern-Simons modified gravity
Abstract We generalize the Chern-Simons modified gravity to the metric-affine case and
impose projective invariance by supplementing the Pontryagin density with homothetic …

Cosmological hyperfluids, torsion and non-metricity
D Iosifidis - The European Physical Journal C, 2020 - Springer
We develop a novel model for cosmological hyperfluids, that is fluids with intrinsic
hypermomentum that induce spacetime torsion and non-metricity. Imposing the …

Most general theory of 3d gravity: Covariant phase space, dual diffeomorphisms, and more
A bstract We show that the phase space of three-dimensional gravity contains two layers of
dualities: between diffeomorphisms and a notion of “dual diffeomorphisms” on the one hand …
