| contents | The s-wave approximation to the black hole dynamics has attracted considerable attention recently. However, the near-AdS2 geometry of the near-horizon region and decoupling of the non-s-wave modes usually requires a small-temperature limit. In this work we propose the new limit based on the large number of dimensions in which the temperature remains finite, but the s-wave sector may be described by Jackiw-Teitelboim gravity interacting with other modes with vanishingly small coupling. However, we demonstrate that the thermal bath of the tensor modes with non-zero angular momenta collectively produces a significant impact on the two-dimensional theory. |
