Title: Small Scales of Inflation

||
Abstract:
||

In the first part of the talk, I will focus on probing small scales of inflation via gravitational waves. Specifically, I will discuss GWs at interferometers from particle production in axion inflation, then in the second part, I will focus on the induced GWs from enhanced density perturbations and imprints of primordial non-Gaussianity on the spectrum. Finally, I will touch on the robust conclusions about the perturbations, primordial black holes, and supermassive BH seeds in the presence of null-detection of any signatures.
