Out-of-time-ordered Correlators in de Sitter Revisited
Alexey Milekhin, Vladimir Narovlansky, Jiuci Xu
We study the 4-point out-of-time-ordered correlator (OTOC) of scalar fields using the eikonal approximation to gravity around a de Sitter background. It can be defined in a gauge-i…
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…
On scrambling, tomperature and superdiffusion in de Sitter space
Alexey Milekhin, Jiuci Xu
This paper investigates basic properties of the de Sitter static patch using simple two-point functions in the probe approximation. We find that de Sitter equilibrates in a superdi…
Revisiting Brownian SYK and its possible relations to de Sitter
Alexey Milekhin, Jiuci Xu
We revisit Brownian Sachdev-Ye-Kitaev model and argue that it has emergent energy conservation overlooked in the literature before. We solve this model in the double-scaled regime…
