The TsT/TTbar Correspondence: A Top-Down Approach of Non-AdS Holography

This lecture explores the TsT/TTbar correspondence as a model of non-AdS holography derived from string theory. Discover how Type IIB string theory on AdS₃ × N with NS-NS three-form flux can be transformed through TsT transformations (T-duality, shift, and another T-duality) to create an asymptotically flat spacetime with a linear dilaton in the string frame. Learn about the holographic dual of this configuration and its relationship to single-trace TTbar-deformed conformal field theory in two dimensions. Examine key aspects of this theoretical model including the spectrum, black holes, symmetries, and correlation functions as presented by Wei Song from the Simons Foundation.
