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 …

We review the spectral theory of soliton gases in integrable dispersive hydrodynamic
systems. We first present a phenomenological approach based on the consideration of …

We review the recent advances on exact results for dynamical correlation functions at large
scales and related transport coefficients in interacting integrable models. We discuss Drude …

We study systems in arbitrary space-time dimensions where matter, deformed by TT‾-like
irrelevant operators, is coupled to gravity in the Palatini formalism. The dynamically …

A bstract In this work, we investigate the time evolution of the pseudo-(Rényi) entropy after
local primary operator quenches in 2D CFTs with\(T\overline {T}/J\overline {T}\)-deformation …

We review recent results on an exactly solvable model of nonequilibrium statistical
mechanics, specifically the classical rule 54 reversible cellular automaton and some of its …

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 …

A bstract In two recent papers [1, 2] we have proposed a program of study which allows us to
compute the correlation functions of local and semi-local fields in generalised\(\textrm …

In this paper, we propose a new representation of the minimal form factors in integrable
quantum field theories. These are solutions of the two-particle form factor equations, which …
