Abstract: (APS)
Pole skipping has been discussed in black-hole backgrounds, but we point out that pole skipping exists even in a non-black-hole background, the anti–de Sitter soliton. For black holes, the pole-skipping points are typically located at imaginary Matsubara frequencies ω=-(2πT)ni with an integer n. The anti–de Sitter soliton is obtained by the double Wick rotation from a black hole. As a result, the pole-skipping points are located at qz=-(2πn)/l, where l is the S1 periodicity and qz is the S1 momentum. The “chaotic” and the “hydrodynamic” pole-skipping points lie in the physical region. We also propose a method to identify all pole-skipping points instead of the conventional method.
