On Cosmological Correlators with Boundary Contributions
Yanjiao Ma, Dong-Gang Wang, Xiangwei Wang +2
Cosmological correlators receive contributions from both field interactions in the bulk of quasi-de Sitter (dS) spacetime and boundary terms at the end of inflation. While most of…

Elko as an inflaton candidate
Xinglong Chen, Cheng-Yang Lee, Yanjiao Ma +3
Elko is a spin-half fermion with a two-fold Wigner degeneracy and Klein-Gordon dynamics. In this paper, we show that in a spatially flat FLRW space-time, slow-roll inflation can be…

Survival of the Fittest: Testing Superradiance Termination with Simulated Binary Black Hole Statistics
Hui-Yu Zhu, Xi Tong, Giorgio Manzoni +1
The superradiance instability of rotating black holes leads to the formation of an ultralight boson cloud with distinctive observational signatures, making black holes an effective…
