Out-of-time-ordered Correlators in de Sitter Revisited
Alexey Milekhin, Vladimir Narovlansky, Jiuci Xu
The paper computes four‑point out‑of‑time‑ordered correlators of scalar fields in de Sitter space using the eikonal approximation to gravity, identifies an infrared issue at loop l…

Generalized Free Fields in de Sitter from 1D CFT
Kanato Goto, Alexey Milekhin, Herman Verlinde +1
We show that a pair of identical large 1D CFTs, like the low-energy limit of the SYK model or a line-defect inside a higher dimensional CFT, contains a natural sub-algebra of o…
