报告摘要：

The TsT/TTbar correspondenceI is a toy model of holographic duality beyond the AdS/CFT correspondence. The model can built by starting from IIB string theory on AdS3 with NS-NS three form flux, which is holographically dual to a two dimensional CFT. Performing TsT transformations( T-duality, shift, and T-duality) in the bulk, we can obtain black black solutions which interpolate BTZ black holes in the IR and linear dilaton background in the UV. The holographic dual is conjectured to be a single trace TTbar deformed CFT. As supporting evidence, we find a matching of the deformed spectrum, the thermodynamics, and a critical value of the deformation parameter.
