Integrability of generalised type II defects in affine Toda field theory
Journal of High Energy Physics, 2017 The Liouville integrability of the generalised type II defects is investigated. Full integrability is not considered, only the existence of an infinite number of conserved quantities associated with a system containing a defect.

The full analytic trans-series in integrable field theories
Physics Letters B, 2023 We analyze a family of generalized energy densities in integrable quantum field theories in the presence of an external field coupled to a conserved charge.

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.

Momentum conserving defects in affine Toda field theories
Journal of High Energy Physics, 2017 Type II integrable defects with more than one degree of freedom at the defect are investigated. A condition on the form of the Lagrangian for such defects is found which ensures the existence of a conserved momentum in the presence of the defect.

The non-chiral intermediate Heisenberg ferromagnet equation
Journal of High Energy Physics, 2022 We present and solve a soliton equation which we call the non-chiral intermediate Heisenberg ferromagnet (ncIHF) equation. This equation, which depends on a parameter δ > 0, describes the time evolution of two coupled spin densities propagating on the ...

Integrable Deformations of Sine-Liouville Conformal Field Theory and Duality [PDF]
, 2017 We study integrable deformations of sine-Liouville conformal field theory. Every integrable perturbation of this model is related to the series of quantum integrals of motion (hierarchy).

Defects in the supersymmetric mKdV hierarchy via Bäcklund transformations
Journal of High Energy Physics, 2018 The integrability of the N=1 $$ \mathcal{N}=1 $$ supersymmetric modified Korteweg de-Vries (smKdV) hierarchy in the presence of defects is investigated through the construction of its super Bäcklund transformation. The construction of such transformation

TOPOLOGICAL FIELD THEORIES AND THE PERIOD INTEGRALS [PDF]
Modern Physics Letters A, 1993 We discuss topological Landau-Ginzburg theories coupled to two-dimensional topological gravity. We point out that the basic recursion relations for correlation functions of the two-dimensional gravity have exactly the same form as the Gauss-Manin differential equations for the period integrals of superpotentials.
