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 obtain microstates accounting for the Gibbons-Hawking entropy in dS 3, along
with a subleading logarithmic correction, from the solvable T\(\overline {T}\)+ Λ 2 deformation …

A bstract The construction of exactly-solvable models has recently been advanced by
considering integrable\(T\overline {T}\) deformations and related Hamiltonian deformations …

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 …

A bstract We investigate a new approach to holography in asymptotically AdS spacetimes, in
which time rather than space is the emergent dimension. By making a sufficiently large T 2 …

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 …

We introduce and study a novel class of classical integrable many-body systems obtained
by generalized TT¯ deformations of free particles. Deformation terms are bilinears in …

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 Defining complexity in quantum field theory is a difficult task, and the main
challenge concerns going beyond free models and associated Gaussian states and …

A bstract We provide a simple geometric meaning for deformations of so-called\(T\overline
{T}\) type in relativistic and non-relativistic systems. Deformations by the cross products of …
