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 ,…

Hidden simplicity in AdS spinning Mellin amplitudes via scaffolding
Song He, Xiang Li, Yuyu Mo +1
We uncover surprising hidden simplicity in Mellin amplitudes for tree-level AdS holographic correlators for spinning operators, such as AdS "gluons" and "gravitons" (spin 1 and 2).…

Heptagon Symbols at Five Loops and All-Loop Sequences
Song He, Xuhang Jiang, Xiang Li +1
We revisit the symbol bootstrap program for the seven-particle MHV and NMHV amplitudes in planar super-Yang-Mills (SYM) based on the alphabet associated with the $E…
