Description

We introduce a method of reverse holography by which a bulk metric is shown to arise from locally computable multiscale correlations of a boundary quantum field theory (QFT). The metric is obtained from the Petz-Rényi mutual information defined with input correlations computed from the continuous wavelet transform. We show for free massless fermionic and bosonic QFTs that the emerging metric is asymptotically anti-de Sitter space (AdS), and that the parameters fixing the geometry are tunable by changing the chosen wavelet basis. The method is applicable to a variety of boundary QFTs that need not be conformal field theories, such as theories with mass or temperature for which we compute the emergent geometries.
