Theories of gravity with nonminimal matter-curvature coupling and the de Sitter swampland conjectures
Orfeu Bertolami, Cláudio Gomes, Paulo M. Sá
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 b…
Quantum kinetic theory of Jeans instability in non-minimal matter-curvature coupling gravity
Cláudio Gomes, Kamel Ourabah
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 functi…
Cassini and extra force constraints to nonminimally coupled gravity with screening mechanism
Riccardo March, Orfeu Bertolami, Marco Muccino +2
We consider a nonminimally coupled curvature-matter gravity theory at the Solar System scale. Both a fifth force of Yukawa type and a further non-Newtonian extra force that arises…
From Quantum Field Theory to Quantum Mechanics
Nuno Barros e Sá, Cláudio Gomes
We construct the algebra of operators acting on the Hilbert spaces of Quantum Mechanics for systems of identical particles from the field operators acting in the Fock space of…
Stability Conditions for the Horndeski Scalar Field Gravity Model
Cláudio Gomes, Orfeu Bertolami
We constrain the viable models of Horndeski gravity, written in its equivalent Generalised Galileon version, by resorting to the Witten positive energy theorem. We find that the fr…
A note on the comments of arXiv:2003.10154 [gr-qc] to our paper Nonminimally Coupled Boltzmann Equation I: Foundations (arXiv:2002.08184 [gr-qc])
Orfeu Bertolami, Cláudio Gomes
In this note we comment on remarks about our recent effort to understand the specificities of the Boltzmann equation in the context of the alternative theories of gravity with non-…
