abstract

We explore the action principle for the holographic $T\bar{T}$-deformation. We develop a scheme in which one can holographically reproduce the action of the Liouville theory deformed by $T\bar{T}$-insertion. This scheme necessitates considering the bending energy of the finite cut-off surface. Following our proposal, one observes a perfect match between the actions of deformed theory on the field theory and gravity sides.

    hep-th 2025-08 conditional novelty 6.0 of 10

    The Euclidean on-shell action for linear-dilaton three-dimensional string backgrounds yields a spacetime mass whose square-root form matches the TT-deformed CFT energy formula.

    hep-th 2025-07 conditional novelty 5.0 of 10

    The TTbar deformation of an anomalous CFT2 has a working holographic model in topological massive gravity, with a universal deformed spectrum and matching entanglement observables.
