It was noticed many years ago, in the framework of massless RG flows, that the irrelevant composite operator T¯T, built with the components of the energy-momentum tensor, enjoys very special properties in 2D quantum field theories, and can be regarded as a peculiar kind of integrable perturbation. Novel interesting features of this operator have recently emerged from the study of effective string theory models. In this paper we study further properties of this distinguished perturbation. We… 
TT deformation of correlation functions
We study the evolution of correlation functions of local fields in a two-dimensional quantum field theory under the λTT deformation, suitably regularized. We show that this may be viewed in terms of
Prepared for submission to JHEP TT deformation of correlation functions
We study the evolution of correlation functions of local fields in a two-dimensional quantum field theory under the λTT deformation, suitably regularized. We show that this may be viewed in terms of
An integrable Lorentz-breaking deformation of two-dimensional CFTs
It has been recently shown that the deformation of an arbitrary two-dimensional conformal field theory by the composite irrelevant operator T \bar TTT‾, built from the components of the stress
TT¯ deformation of the compactified boson and its interpretation in lattice gauge theory
We study the effective string description of space-like Polyakov loop correlators at finite temperature with the goal of describing the behaviour of the space--like string tension in the vicinity of
TT̄-deformed 1d Bose gas
TT̄ deformation was originally proposed as an irrelevant solvable deformation for 2d relativistic quantum field theories (QFTs). The same family of deformations can also be defined for integrable
A general definition of $JT_a$ -- deformed QFTs
We propose a general path-integral definition of two-dimensional quantum field theories deformed by an integrable, irrelevant vector operator constructed from the components of the stress tensor and

We study the thermodynamic Bethe ansatz (TBA) equations for pure TT¯ perturbations of some simple integrable quantum field theories with a single bosonic or fermionic particle, in particular the

The effective action on long strings, such as confining strings in pure Yang-Mills theories, is well-approximated by the Nambu-Goto action, but this action cannot be exact. The leading possible
