Description
Motivated by primordial black holes as an observational window into primordial spectra on sub-CMB scales, I will discuss some interesting properties of the perturbations generated during multi-field inflation.
Among them: power spectrum features, non-gaussianity — or otherwise — of small perturbations, and the statistics of large, rare, curvature fluctuations ("non-gaussian tails").
