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…

Mass dimension one fermions in FLRW space-time
Cheng-Yang Lee, Haomin Rao, Wenqi Yu +1
Cosmelkology is the study of Elko in cosmology. Elko is a massive spin-half field of mass dimension one. Elko differs from the Dirac and Majorana fermions because it furnishes the…
