Primordial black holes and Scalar-Induced Gravitational Waves formed by inflation potential with non-trivial characteristics
Ruifeng Zheng, Yanqing Xu
The formation of primordial black holes (PBHs) generally requires large density perturbations, which is widely supported by researchers. This paper studies the local coupling prope…
