Quadratic gravity potentials in de Sitter spacetime from Feynman diagrams
Abstract We employ a manifestly covariant formalism to compute the tree-level amputated Green’s function of non-minimally coupled scalar fields in quadratic gravity in a de Sitter background. We study this Green’s function in the adiabatic limit, and construct the classical Newtonian potential. At s...
