Correlation functions of determinant operators in conformal fishnet theory

Journal of High Energy Physics, 2022
We consider scalar local operators of the determinant type in the conformal “fishnet” theory that arises as a limit of gamma-deformed N $$ \mathcal{N} $$ = 4 super Yang-Mills theory.

An operator expansion for integrable quantum field theories [PDF]

, 2012
A large class of quantum field theories on 1 + 1 dimensional Minkowski space, namely, certain integrable models, has recently been constructed rigorously by Lechner. However, the construction is very abstract and the concrete form of local observables in

Type II defects revisited

Journal of High Energy Physics, 2018
Energy and momentum conservation in the context of a type II, purely transmitting, defect, within a single scalar relativistic two-dimensional field theory, places a severe constraint not only on the nature of the defect but also on the potentials for ...

Electric network and Hirota type 4-simplex maps

Journal of High Energy Physics
Bazhanov-Stroganov (4-simplex) maps are set-theoretical solutions to the 4-simplex equation, namely the fourth member of the family of n-simplex equations, which are fundamental equations of mathematical physics.

TBA equations and resurgent Quantum Mechanics

Journal of High Energy Physics, 2019
We derive a system of TBA equations governing the exact WKB periods in one-dimensional Quantum Mechanics with arbitrary polynomial potentials. These equations provide a generalization of the ODE/IM correspondence, and they can be regarded as the solution

Towards the Construction of Wightman Functions of Integrable Quantum Field Theories

, 2004
The purpose of the ``bootstrap program'' for integrable quantum field theories in 1+1 dimensions is to construct a model in terms of its Wightman functions explicitly.

Consistent string backgrounds and completely integrable 2D field theories [PDF]

, 1995
After reviewing the $\beta$-function equations for consistent string backgrounds in the $\sigma$-model approach, including metric and antisymmetric tensor, dilaton and tachyon potential, we apply this formalism to WZW models.

Boundary Flows in general Coset Theories

, 1998
In this paper we study the boundary effects for off-critical integrable field theories which have close analogs with integrable lattice models. Our models are the $SU(2)_{k}\otimes SU(2)_{l}/SU(2)_{k+l}$ coset conformal field theories perturbed by ...

Gauging the diamond: integrable coset models from twistor space

Journal of High Energy Physics
Recent work has shown that certain integrable and conformal field theories in two dimensions can be given a higher-dimensional origin from holomorphic Chern-Simons in six dimensions. Along with anti-self-dual Yang-Mills and four-dimensional Chern-Simons,

Local charges in involution and hierarchies in integrable sigma-models

Journal of High Energy Physics, 2017
Integrable σ-models, such as the principal chiral model, ℤ T $$ {\mathbb{Z}}_T $$ -coset models for T ∈ ℤ ≥ 2 $$ T\in {\mathbb{Z}}_{\ge 2} $$ and their various integrable deformations, are examples of non-ultralocal integrable field theories described by
