Probing bulk geometry via pole skipping: from static to rotating spacetimes
Cheng Ran, Zhenkang Lu, Shao-Feng Wu
We investigate an analytical framework for reconstructing bulk geometries from pole-skipping data. Previously, this method enabled the recursive recovery of near-horizon metric der…

Bulk Spacetime Encoding via Boundary Ambiguities
Zhenkang Lu, Cheng Ran, Shao-feng Wu
We propose a method to reconstruct the metric and its arbitrary-order derivatives at the horizon for any static, planar-symmetric black hole, using an infinite set of discrete pole…

The Algebraic Structure Underlying Pole-Skipping Points
Zhenkang Lu, Cheng Ran, Shao-feng Wu
The holographic Green's function becomes ambiguous, taking the indeterminate form `', at an infinite set of special frequencies and momenta known as ``pole-skipping points''.…
