Title: Quantum corrections to the near-extremal thermodynamics of (warped) BTZ black holes

Abstract: We study one-loop effects in BTZ and warped BTZ black holes, focusing on eigenmodes that become zero modes in the extremal throat. Our analysis is formulated in three-dimensional Topologically Massive Gravity. We compare the near-horizon and full-geometry eigenvalue problems and determine how the Schwarzian and rotational sectors are lifted at small temperature. By generalizing perturbation theory, we resolve a mismatch between the near-horizon and full-geometry rotational sectors previously reported in the literature. We show that rotational modes probe the throat as an open system, so their contribution cannot be determined from the throat alone but depends on boundary conditions in the full geometry.
