Complete background cosmology of parity-even quadratic metric-affine gravity
Thomas Dyer, Will Barker, Damianos Iosifidis
The cosmology of metric-affine gravity is studied for the general, parity preserving action quadratic in curvature, torsion and non-metricity. The model contains 27 a priori indepe…
Friedmann cosmology with hyperfluids
Ilaria Andrei, Damianos Iosifidis, Laur Järv +1
In metric-affine gravity, both the gravitational and matter actions depend not just on the metric, but also on the independent affine connection. Thus matter can be modeled as a hy…
Extended Metric-Affine Gravity with Dynamical Connection in Vacuum
Damianos Iosifidis
We extend the usual vacuum Metric-Affine Gravity by supplementing it with all parity even quadratic invariants in torsion and non-metricity. As we show explicitly this suppl…
Relativistic interacting fluids in cosmology
Damianos Iosifidis, Erik Jensko, Tomi S. Koivisto
Motivated by cosmological applications for interacting matters, an extension of the action functional for relativistic fluids is proposed to incorporate the physics of non-adiabati…
Statistical conformal Killing Vector Fields for FLRW Space-Time
Esmaeil Peyghan, Leila Nourmohammadifar, Damianos Iosifidis
The classification of conformal Killing vector fields for FLRW space-time from Riemannian point of view was done by Maartens-Maharaj in \cite{Maartens1986}. In this paper, we intro…
Into the MAG-verse or: Cosmology of the Complete Quadratic Metric-Affine Gravity
Damianos Iosifidis, Konstantinos Pallikaris
We study the cosmology of the complete quadratic (in torsion and nonmetricity) metric-affine gravity. Namely, we add to the scalar-curvature gravitational Lagrangian, the 17 indepe…
