Genus-Two Contributions to Late-Time Correlators in JT Gravity
Masayoshi Sato
In this work, we analyze the late-time two-point correlation function in Jackiw--Teitelboim gravity, focusing on the genus-two () contribution associated with two baby univers…

Degenerate chords in double-scaled SYK
Kazuo Hosomichi, Masayoshi Sato
The matter operator in the double-scaled SYK model exhibits special properties when its dimension is analytically continued to -1/2. At this dimension, the operator is in a degener…

What happens due to the baby universe effect in JT gravity? -Analysis of correlation functions and ERB length at late time using three approaches-
Masayoshi Sato
We analyze the correlation function in JT gravity using three approaches: by summing over all geodesics connecting boundary operators, integrating over the region of moduli space d…
