Equivalence principle violation in nonminimally coupled gravity and constraints from lunar laser ranging

R March, O Bertolami, M Muccino, S Dell'Agnello - Physical Review D, 2024 - APS
We analyze the dynamics of the Sun-Earth-Moon system in the context of a particular class
of theories of gravity where curvature and matter are nonminimally coupled. These theories …

Quantum kinetic theory of Jeans instability in non-minimal matter-curvature coupling gravity

C Gomes, K Ourabah - The European Physical Journal C, 2023 - Springer
We present a quantum treatment of the Jeans gravitational instability in the Newtonian limit
of the non-minimal matter-curvature coupling gravity model. By relying on Wigner functions …

Theories of gravity with nonminimal matter-curvature coupling and the de Sitter swampland conjectures

O Bertolami, C Gomes, PM Sá - Physical Review D, 2023 - APS
We discuss, in the context of alternative theories of gravity with nonminimal coupling
between matter and curvature, if inflationary solutions driven by a single scalar field can be …

Cassini and extra force constraints to nonminimally coupled gravity with a screening mechanism
