Renormalons in integrable field theories [PDF]
Journal of High Energy Physics, 2020 In integrable field theories in two dimensions, the Bethe ansatz can be used to compute exactly the ground state energy in the presence of an external field coupled to a conserved charge.

Integrable Field Theories with Defects [PDF]
Czechoslovak Journal of Physics, 2006 The structure of integrable field theories in the presence of defects is discussed in terms of boundary functions under the Lagrangian formalism. Explicit examples of bosonic and fermionic theories are considered.

Noncommutative Integrable Field Theories in 2d [PDF]
Nuclear Physics B, 2002 We study the noncommutative generalization of (euclidean) integrable models in two-dimensions, specifically the sine- and sinh-Gordon and the U(N) principal chiral models. By looking at tree-level amplitudes for the sinh-Gordon model we show that its na\"

Quantum Quenches in Integrable Field Theories [PDF]
New Journal of Physics, 2010 We study the non equilibrium time evolution of an integrable field theory in 1+1 dimensions after a sudden variation of a global parameter of the Hamiltonian.

Deformations of quantum field theories and integrable models [PDF]
, 2011 Deformations of quantum field theories which preserve Poincar\'e covariance and localization in wedges are a novel tool in the analysis and construction of model theories.

Integrable field theories and their CCFT duals
Journal of High Energy Physics, 2023 We compute the Mellin transforms of various two-dimensional integrable S-matrices, providing the first explicit, non-perturbative realizations of celestial CFT.

Symplectic deformations of integrable field theories and AdS/CFT [PDF]
Physics Letters B, 2014 Relativistic integrable field theories like the sine-Gordon equation have an infinite set of conserved charges. In a light-front formalism these conserved charges are closely related to the integrable modified KdV hierarchy at the classical level.

Scaling limits of integrable quantum field theories [PDF]
Reviews in Mathematical Physics, 2011 Short distance scaling limits of a class of integrable models on two-dimensional Minkowski space are considered in the algebraic framework of quantum field theory.

Integrability of coupled conformal field theories [PDF]
Nuclear Physics B, 1998 The massive phase of two-layer integrable systems is studied by means of RSOS restrictions of affine Toda theories. A general classification of all possible integrable perturbations of coupled minimal models is pursued by an analysis of the (extended) Dynkin diagrams.
