Memory burden effect of regular primordial black holes
Jin-Rong Du, Zi-Zhuo Zhang, Nan Li
Primordial black holes (PBHs) have attracted intensive research interest as a promising candidate of dark matter. However, because of the Hawking radiation, the PBHs lighter than $…

Constraints on the inflaton potential from scalar-induced gravitational waves and primordial black holes
Shi-jie Wang, Nan Li
A plateau on the background inflaton potential can lead cosmic inflation into an ultraslow-roll phase, greatly enhancing the primordial power spectrum on small scal…

Primordial black holes from the ultraslow-roll phase in the inflaton--curvaton mixed field inflation
Bing-Yu Su, Nan Li, Lei Feng
Primordial black holes (PBHs) are a promising candidate for dark matter, as they can form in the very early universe without invoking new particle physics. This work explores PBH f…
