High-Order Pole-Skipping in Near-Extremal Holography
Xiang Li, Haiming Yuan, Xian-Hui Ge
We develop a systematic analytic method for studying high-order pole-skipping in near-extremal holographic black holes. In the near-extremal regime, approaching the limit ,…

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 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 , where and…
