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 consider a one-parameter family of composite fields—bi-linear in the
components of the stress-energy tensor—which generalise the\(\mathrm {T}\overline …

Given a model for self-dual nonlinear electrodynamics in four spacetime dimensions, any
deformation of this theory which is constructed from the duality-invariant energy-momentum …

A bstract In a theory of quantum gravity, states can be represented as wavefunctionals that
assign an amplitude to a given configuration of matter fields and the metric on a spatial slice …

A bstract The conformal symmetry algebra in 2D (Diff (S 1)⊕ Diff (S 1)) is shown to be
related to its ultra/non-relativistic version (BMS 3≈ GCA 2) through a nonlinear map of the …

A bstract The\(T\overline {T}\) deformation is a solvable irrelevant deformation whose
properties depend on the sign of the deformation parameter μ. In particular,\(T\overline {T}\) …

This paper reviews and extends the recently discovered connections between marginal and
irrelevant stress-energy tensor deformations and gravity theories in arbitrary space-time …

A bstract In this work we elaborate on holographic description of the path-integral
optimization in conformal field theories (CFT) using Hartle-Hawking wave functions in Anti …

In this work, we study the holographic entanglement entropy in AdS 3 gravity with the certain
mixed boundary condition, which turns out to correspond to TT¯-deformed 2D CFTs. By …
