Covariant One-Loop Corrections from a Non-Covariant Expansion: The Scalar Field Case
Lucas Ducastelo de C. C. Lima, Riccardo Fecchio
We compute the one-loop correction to the non-minimal coupling of a scalar field theory to gravity, induced by a quartic self-interaction. We adopt the non-covariant framework of l…

Trace anomaly, effective approach, and gravitational potential
Riccardo Fecchio, Ilya L. Shapiro
We explore and discuss corrections to the Newton potential from the quantum effects of conformal matter fields. In this special case, one can compare different approaches, includin…
