Pole inflation from extended metric-affine gravity
Damianos Iosifidis, Sotirios Karamitsos
We study inflation in the framework of extended metric-affine F(R) gravity, where all even-parity quadratic invariants of torsion and non-metricity are included in the Lagrangian a…
Non-local Metric-Affine Gravity
Salvatore Capozziello, Damianos Iosifidis
Non-local gravity can potentially solve several problems of gravitational field both at Ultra-Violet and Infra-Red scales. However, such an approach has been formulated mainly in m…
Lagrangian Dynamics of Spinning Pole-Dipole-Quadrupole Particles in Metric-Affine Geometries
Damianos Iosifidis
We construct the Lagrangian formulation of a micro-structured spinning, dilating and shearing (deformable) test body, moving in arbitrary non-Riemannian backgrounds possessing all…
Friedmann cosmology with hyperfluids of constant equation of state
Ilaria Andrei, Damianos Iosifidis, Laur Järv +1
We discuss some aspects of cosmology in metric-affine theories of gravity where metric and affine connection are independent variables. Such constructions, apart from the usual ene…
On the role of the Parity Violating Hojman--Holst term in Gravity Theories
Damianos Iosifidis
We study Parity Violating Gravity Theories whose gravitational Lagrangian is a generic function of the scalar curvature and the parity odd curvature pseudoscalar, commonly known as…
Cosmology of Cubic Poincaré Gauge gravity
Sebastian Bahamonde, Rebecca Briffa, Konstantinos Dialektopoulos +2
In this paper, we study flat FLRW cosmology for a Poincaré gauge theory containing cubic invariants that is free from ghosts in arbitrary backgrounds in the axial and vector sector…
