Resurgence and 1/N Expansion in Integrable Field Theories [PDF]
Journal of High Energy Physics, 2021 In theories with renormalons the perturbative series is factorially divergent even after restricting to a given order in 1/N, making the 1/N expansion a natural testing ground for the theory of resurgence.

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.

5d 2-Chern-Simons theory and 3d integrable field theories [PDF]
Communications in Mathematical PhysicsThe 4-dimensional semi-holomorphic Chern-Simons theory of Costello and Yamazaki provides a gauge-theoretic origin for the Lax connection of 2-dimensional integrable field theories. The purpose of this paper is to extend this framework to the setting of 3-

On space of integrable quantum field theories [PDF]
Nuclear Physics B, 2017 We study deformations of 2D Integrable Quantum Field Theories (IQFT) which preserve integrability (the existence of infinitely many local integrals of motion). The IQFT are understood as “effective field theories”, with finite ultraviolet cutoff. We show

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.

Quantum quenches in integrable field theories [PDF]
, 2009 We study the non-equilibrium time evolution of an integrable field theory in 1+1 dimensions after sudden variation of a global parameter of the Hamiltonian.

Noncommutative integrable field theories in 2d [PDF]
, 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\"

Integrable field theories with defects [PDF]
, 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.

ON A SYSTEMATIC APPROACH TO DEFECTS IN CLASSICAL INTEGRABLE FIELD THEORIES [PDF]
, 2007 We present an inverse scattering approach to defects in classical integrable field theories. Integrability is proved systematically by constructing the generating function of the infinite set of modified integrals of motion.
