Classically integrable field theories with defects [PDF]

International Journal of Modern Physics A, 2003
Some ideas and remarks are presented concerning a possible Lagrangian approach to the study of internal boundary conditions relating integrable fields at the junction of two domains.

Scaling limits of integrable quantum field theories [PDF]

, 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.

Coupling integrable field theories to mechanical systems at the boundary [PDF]

, 2001
We present an integrable Hamiltonian which describes the sinh-Gordon model on the half line coupled to a non-linear oscillator at the boundary. We explain how we apply Sklyanin's formalism to a dynamical reflection matrix to obtain this model.

Integrable lattice models from four-dimensional field theories [PDF]

, 2013
This note gives a general construction of an integrable lattice model (and a solution of the Yang-Baxter equation with spectral parameter) from a four-dimensional field theory which is a mixture of topological and holomorphic.

Equilibration properties of classical integrable field theories [PDF]

Journal of Statistical Mechanics: Theory and Experiment, 2016
We study the equilibration properties of classical integrable field theories at a finite energy density, with a time evolution that starts from initial conditions far from equilibrium.

Deformations of Fermionic Quantum Field Theories and Integrable Models [PDF]

, 2012
Considering the model of a scalar massive Fermion, it is shown that by means of deformation techniques it is possible to obtain all integrable quantum field theoretic models on two-dimensional Minkowski space which have factorizing S-matrices ...

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.

Four-dimensional Chern–Simons theory and integrable field theories [PDF]

Journal of Physics A: Mathematical and Theoretical, 2021
These lecture notes concern the semi-holomorphic 4D Chern–Simons theory and its applications to classical integrable field theories in 2D and in particular integrable sigma-models.
