Primordial black holes are gaining a renewed interest as a source of various phenomena in our early universe, and are regarded to be appealing probes for the curvature perturbation at small scales. These enhanced curvature perturbations also lead to second order gravitational waves, with many ranges of frequencies within reach of future observations. Here I analyze the curvature perturbation enhancement in the Higgs-$R^2$ model, and present its implications on primordial black holes and gravitational waves.
