The Probe of Curvature in the Lorentzian AdS${}_2$/CFT${}_1$ Correspondence

Abstract

We establish the Lorentzian AdS${}_2$/CFT${}_1$ correspondence from a reconstruction of all bulk points through the kinematic-space approach. The OPE block is exactly a bulk local operator. We formulate the correspondence between the bulk propagator in the non-interacting scalar field theory and the conformal block in CFT${}_1$. When we consider the stress tensor, the variation probes the variation of AdS${}_2$ metric. The reparameterization provides the asymptotic boundary of the bulk spacetime as in the derivation of the Schwarzian theory from two-dimensional dilaton gravity theory. Finally, we find the AdS${}_2$ Riemann curvature tensor based on the above consistent check.
