Are primordial black holes produced by entropy perturbations in single field inflationary models?
We show that in single field inflationary models the super-horizon evolution of curvature perturbations on comoving slices &calR;, which can cause the production of primordial black holes (PBH), is not due to entropy perturbations, but to the background evolution effect on the conversion between...
