Pole-skipping in the de Sitter horizon structure

Haiming Yuan, Xian-Hui Ge, Keun-Young Kim

We study the pole-skipping structure of incoming waves near the cosmic horizon $r = r_{c}$ in de Sitter (dS) spacetime. We find that the scalar field with spin-0, the Dirac field with…

Pole-skipping in two-dimensional de Sitter spacetime and double-scaled SYK model

Haiming Yuan, Xian-Hui Ge, Keun-Young Kim

We develop the pole-skipping structure in de Sitter (dS) spacetime and find that their leading frequencies satisfy the relation $I ¨ _{d S} = i 2 I ¨ T_{d S} (1 - s)$ , where $T_{d S} = 1/2 I ¨ L$ and…
