An Ostrogradsky Instability Analysis of Non-minimally Coupled Weyl Connection Gravity Theories
Rodrigo Baptista, Orfeu Bertolami
We study the Hamiltonian formalism of the non-minimally coupled Weyl connection gravity (NMCWCG) in order to check whether Ostrogradsky instabilities are present. The Hamiltonian o…

Cosmological Solutions of the Non-minimally Coupled Weyl Connection Gravity Theories
Rodrigo Baptista, Orfeu Bertolami
We consider a non-minimally coupled curvature-matter gravity model (NMC) with a Weyl connection, a theory referred to as non-minimally coupled Weyl connection gravity (NMCWCG). The…

Constraining a nonminimally coupled curvature-matter gravity model with ocean experiments
Riccardo March, Orfeu Bertolami, Marco Muccino +2
We examine the constraints on the Yukawa regime from the non-minimally coupled curvature-matter gravity theory arising from deep underwater ocean experiments. We consider the geoph…
