Super $T\bar{T}$ deformation and the RNS non-critical superstring

In this paper we review the super $T\bar{T}$ deformation of $\mathcal{N}=(1,1)$ theories in the superspace formulation, alongside its interpretation in the context of noncritical string theory. By combining the superspace approach with concepts from the study of super-Riemann surfaces, we demonstrate that super $T\bar{T}$ deformations in superspace can be naturally interpreted as a noncritical RNS superstring theory. We also propose a possible interpretation of the super $T\bar{T}$ deformations as 2D supergravity in the superspace through some field redefinitions.
