Primordial Black Holes from Sound Speed Resonance during Inflation
Yi-Fu Cai, Xi Tong, Dong-Gang Wang +1
We report on a novel phenomenon of the resonance effect of primordial density perturbations arisen from a sound speed parameter with an oscillatory behavior, which can generically…

Connections between Minkowski and Cosmological Correlation Functions
Shek Kit Chu, Mang Hei Gordon Lee, Shiyun Lu +3
We show how cosmological correlation functions of massless fields can be rewritten in terms of Minkowski correlation functions, by extracting symmetry-breaking operators from the c…

Warm Quasi-Single Field Inflation
Xi Tong, Yi Wang, Siyi Zhou
We study quasi-single field inflation with a warm inflation background. The thermal effects at small scales can sufficiently enhance the magnitude of the primordial standard clock…
