Abstract
The TsT transformation of string theory on AdS$_3\times {\cal N}$ with NS-NS flux has been conjectured to be holographically dual to a single trace TTbar deformation of the symmetric orbifold CFT on the AdS$_3$ boundary. In this talk, we present a non-perturbative calculation of two-point correlation functions using string theory and demonstrate their consistency with those of the TTbar deformation. At un-twisted sector, the non-perturbative result satisfies the Callan-Symanzik equation for double trace TTbar deformed CFT derived by Cardy. We also perform conformal perturbations on both the worldsheet CFT and the symmetric orbifold CFT as a sanity check. The perturbative and non-perturbative matching between results on the two sides provides further evidence for the conjectured TsT/TTbar correspondence. This talk is based on the joint work with W. Cui, W. Song and J. Wang.Speaker
Dr. Hongfei Shu obtained his PhD from Tokyo Institute of Technology in 2019. He Worked as a Postdoc at Nordita during 2019-2021. Currently, he is a Postdoc at BIMSA. His main research interest includes integrability, AdS/CFT correspondence and other non-perturbative method.
