From Frame Covariance to the Swampland Distance Conjecture
Sotirios Karamitsos, Benjamin Muntz
Field space geometry plays a central role within the Swampland Programme, most notably in the various Distance Conjectures. However, for gravitational EFTs, this geometry is not un…

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…

Quasi-Palatini Formulation of Scalar-Tensor Gravity
Sotirios Karamitsos
The Palatini formulation has been successful in the development of several alternative theories of gravity. It is well understood that the Palatini and metric formulations are equi…
