Non-linear equation of motion for higher curvature semiclassical gravity

Non-linear equation of motion for higher curvature semiclassical gravity

We derive the non-linear semiclassical equation of motion for a general diffeomorphism-invariant theory of gravity by leveraging the thermodynamic properties of closed causal horizons. Our work employs two complementary approaches. The first approach utilizes perturbative quantum gravity applied to...
