Comments on single trace $T\bar{T}$ and other current-current deformations

Gaston Giribet, Julio Oliva, Ricardo Stuardo

String theory on AdS${}_3$ with NS-NS fluxes admits a solvable irrelevant deformation which is close to the $T\bar{T}$ deformation of the dual CFT${}_2$. This consists of deforming the…
