This is a pedagogical review on TT deformation of two dimensional quantum field theories. It
is based on three lectures which the author gave at ITP-CAS in December 2018. This review …

A bstract We study the correlation functions of local operators in unitary\(\textrm {T}\overline
{\textrm {T}}\)-deformed field theories, using their formulation in terms of Jackiw-Teitelboim …

We study interacting theories of N left-moving and N¯ right-moving Floreanini-Jackiw
bosons in two dimensions. A parametrized family of such theories is shown to enjoy …

A bstract The\(T\overline {T}\) deformation of a 2 dimensional field theory living on a curved
space-time is equivalent to coupling the undeformed field theory to 2 dimensional 'ghost …

We quantize the ModMax oscillator, which is the dimensional reduction of the modified
Maxwell theory to one spacetime dimension. We show that the propagator of the ModMax …

In this paper, we investigate the correlation functions of the conformal field theory (CFT) with
the TT¯ deformation on a torus in terms of the perturbative CFT approach, which is the …

A bstract Pure gravity in AdS 3 is a theory of boundary excitations, most simply expressed as
a constrained free scalar with an improved stress tensor that is needed to match the Brown …

We show that $ T\bar T, J\bar T $ and $ J T_a $-deformed classical CFTs possess an infinite
set of symmetries that take the form of a field-dependent generalization of two-dimensional …

A bstract We investigate the\(T\overline {T}\)-like flows for non-linear electrodynamic theories
in D (= 2n)-dimensional spacetime. Our analysis is restricted to the deformation problem of …

We study TT¯-deformed O (N) scalar field theory in two-dimensional spacetime using the
functional renormalization group. We derive the β functions for the couplings in the system …
