AdS segment and hidden conformal symmetry in general non-extremal black holes

TL;DR

This paper shows that the near-horizon regions of general non-extremal black holes can be modeled as segments of AdS space, explaining the origin of hidden conformal symmetries observed in previous studies.

Contribution

It reveals that the hidden conformal symmetry arises from viewing near-horizon geometries as AdS segments instead of Rindler space, providing a new geometric perspective.

Findings

Near-horizon geometries of non-extremal black holes are AdS segments.

Hidden conformal symmetries are linked to AdS segment geometry.

Previous observations of conformal symmetry are explained by this geometric interpretation.

Abstract

It is demonstrated that the near-horizon geometry of general non-extremal black holes can be described by a portion of AdS space. We show that the reason why hidden conformal symmetries near horizons of general non-extremal black holes are achieved in previous works is that the near-horizon geometries have been equivalently taken as these AdS segments rather than simply the Rindler space.
