$T\overline{T}$ deformations of non-Lorentz invariant field theories

Abstract

We point out that the arguments of Zamolodchikov and others on the $T\overline{T}$ and similar deformations of two-dimensional field theories may be extended to the more general non-Lorentz invariant case, for example non-relativistic and Lifshitz-type theories. We derive results for the finite-size spectrum and $S$-matrix of the deformed theories.
