Primordial black holes and secondary gravitational waves from chaotic inflation

Gao, Qing

Chaotic inflation is inconsistent with the observational constraint at 68% CL. Here, we show that the enhancement mechanism with a peak function in the noncanonical kinetic term not only helps the chaotic model V(ϕ) = V₀ϕ^1/3 satisfy the observational constraint at large scales but also enhances the primordial scalar power spe…
