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

We revisit the so-called folded XXZ model, which was treated earlier by two independent
research groups. We argue that this spin-1/2 chain is one of the simplest quantum integrable …

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 …

A bstract The study of\(\textrm {T}\overline {\textrm {T}}\)-perturbed quantum field theories is
an active area of research with deep connections to fundamental aspects of the scattering …

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 …

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 …

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 …

We investigate emergent quantum dynamics of the tilted Ising chain in the regime of a weak
transverse field. Within the leading order perturbation theory, the Hilbert space is fragmented …

A bstract We study the (d+ 2)-dimensional Hyperscaling Violating (HV) geometries in the
presence of both a finite temperature T and a UV cutoff r c. This gravitational system is …
