Observational constraints on inflationary decoherence with polynomial attractor model
Zhongkai Wang, Yungui Gong
The quantum-to-classical transition of inflationary perturbations remains an unresolved fundamental problem, and quantum decoherence is one of the promising solutions. By consideri…

Primordial black holes and scalar-induced gravitational waves from the polynomial attractor model
Zhongkai Wang, Shengqing Gao, Yungui Gong +1
Primordial black holes (PBHs) generated in the early Universe are considered as one of the candidates for dark matter. To produce PBHs with sufficient abundance, the primordial sca…
