Gravitational perturbations as $T\bar{T}$-deformations in 2D dilaton gravity systems

We consider gravitational perturbations of 2D dilaton gravity systems and show that these can be recast into $T\bar{T}$-deformations (at least) under certain conditions, where $T$ means the energy-momentum tensor of the matter field coupled to a dilaton gravity. In particular, the class of theories under this condition includes a Jackiw-Teitelboim (JT) theory with a negative cosmological constant including conformal matter fields.

This is a generalization of the preceding work on the flat-space JT gravity by S.Dubovsky, V.Gorbenko and M.Mirbabayi [arXiv:1706.06604 ].
