Is the NANOGrav signal a hint of dS decay during inflation?
Hao-Hao Li, Gen Ye, Yun-Song Piao
As suggested by the swampland conjectures, de Sitter (dS) space might be highly unstable if it exists at all. During inflation, the short-lived dS states will decay through a casca…

censorship of early dark energy and AdS vacua
Gen Ye, Yun-Song Piao
Present-day temperature of cosmic microwave background has been precisely measured by the FIRAS experiment. We identify that the early dark energy (EDE) (non-negligible aroun…

Is the Hubble tension a hint of AdS phase around recombination?
Gen Ye, Yun-Song Piao
Anti-de Sitter (AdS) vacua, being theoretically important, might have an unexpected impact on the observable universe. We find that in early dark energy (EDE) scenarios the existen…
