Primordial Black Holes from a tiny bump/dip in the Inflaton potential

Understand

Scalar perturbations during inflation can be substantially amplified by tiny features in the inflaton potential.

A bump-like feature behaves like a local speed-breaker and lowers the speed of the scalar field, thereby locally enhancing the scalar power spectrum.
A bump-like feature emerges naturally if the base inflaton potential $V_b(\phi)$ contains a local correction term such as $V_b(\phi)\left[1+\varepsilon(\phi)\right]$ at $\phi=\phi_0$.
The presence of such a localised correction term at $\phi_0$ leads to a large peak in the curvature power spectrum and to an enhanced probability of black hole formation.
