Abstract: (APS)
Recently, it has been shown that many Green’s functions are not unique at special points in complex momentum space using AdS/CFT. This phenomenon is similar to the pole skipping in holographic chaos, and the special points are typically located at ωn=-(2πT)ni with appropriate values of complex wave number qn. We study finite-coupling corrections to special points. As examples, we consider four-derivative corrections to gravitational perturbations and four-dimensional Maxwell perturbations. While ωn is uncorrected, qn is corrected at finite coupling. Some special points disappear at particular values of higher-derivative couplings. Special point locations of the Maxwell scalar and vector modes are related to each other by the electromagnetic duality.
