摘要 (Abstract): 

In this talk, I will explain that the exterior of a planar/spherically/hyperbolically symmetric asymptotically anti-de Sitter static black brane/hole can be reconstructed from its two arbitrary boundary frequency 2-point correlation functions by solving a Gel'fand-Levitan-Marchenko integral equation. A method about how to solve this integral equation is also presented by using BTZ black hole as an example. Since the frequency correlation function is easily handled in experiments and theories, this method not only proposes an explicit method to "directly measure" the corresponding holographic spacetime for a material that has holographic dual but also provides a powerful approach to experimentally check if a system has holographic dual.
