Higher curvature corrections to pole-skipping

Understand

Recent developments have revealed a new phenomenon, i.e.

• the residues of the poles of the holographic retarded two point functions of generic operators vanish at certain complex values of the frequency and momentum.
• This so-called pole-skipping phenomenon can be determined holographically by the near horizon dynamics of the bulk equations of the corresponding fields.
• In particular, the pole-skipping point in the upper half plane of complex frequency has been shown to be closed related to many-body chaos, while those in the lower half plane also places universal and nontrivial constraints on the two point functions.
