It is well known that asymptotically flat Schwarzschild black holes in general relativity in four spacetime dimensions have vanishing induced linear tidal response. We extend this result beyond linear order for the polar sector, by solving the static nonlinear Einstein equations for the perturbations of the Schwarzschild metric and computing the quadratic corrections to the electric-type tidal Love numbers. After explicitly performing the matching with the point-particle effective theory at leading order in the derivative expansion, we show that the Love number couplings remain zero at higher order in perturbation theory.

Multipolar static tidal response of Schwarzschild black holes in cubic gravity: a metric-action derivation of tidal running
In cubic Weyl gravity, the metric-field derivation reproduces the known canonical electric beta functions, proves the quadrupole is the unique non-running electric multipole via an L-6 source factor, and gives explici...

On the logarithmic Love number of black holes beyond general relativity
Logarithmic black hole Love numbers are fixed directly by the Taylor coefficients of the perturbation equation, and perturbative deviations from Schwarzschild/Reissner-Nordström force non-zero running.
