Interacting fluid cosmologies from the metric-affine framework
Fotios K. Anagnostopoulos, Damianos Iosifidis
Metric-affine gravity provides a natural geometric framework in which spacetime curvature, torsion, and non-metricity are treated as independent degrees of freedom, leading to nove…
Scalar field with nonminimal couplings to metric-affine geometry
Ilaria Andrei, Damianos Iosifidis, Laur Järv +1
We study a scalar field nonminimally coupled to metric-affine gravity within actions linear in the affine curvature and containing all independent parity-even and parity-odd terms…
Belinfante-Rosenfeld Symmetrization from Metric-Affine Conservation Laws: Hypermomentum as the Improvement Term -- The Cases of QED and QCD
Damianos Iosifidis
We derive the Belinfante--Rosenfeld symmetrization procedure from the metric-affine conservation law by means of an affine lift of flat-spacetime field theories. Following minimal…
Inflation with Nieh-Yan-like terms in metric-affine gravity
Ilaria Andrei, Christian Dioguardi, Damianos Iosifidis +3
We study single-field slow-roll inflation in metric-affine gravity with a scalar field non-minimally coupled to the non-Riemannian Ricci scalar and to the divergences of the torsio…
Novel Regge-like trajectories for spinning, dilating, hadronic particles
Damianos Iosifidis
We study the of motion of a spinning, dilating particle with hadronic properties moving on a generic geometric background including curvature, torsion, and nonmetricity. In particu…
Friedmann cosmology with fluids and hyperfluids
Ilaria Andrei, Damianos Iosifidis, Laur Järv +1
We discuss flat Friedmann-Lemaitre-Robertson-Walker (FLRW) metric-affine cosmology where the metric and connection as well as the matter energy-momentum and hypermomentum all obey…
