Scattering in Twisted Yangians
Jean Avan, Anastasia Doikou, Nikos Karaiskos
We study the bulk and boundary scattering of the sl(N) twisted Yangian spin chain via the solution of the Bethe ansatz equations in the thermodynamic limit. Explicit expressions fo…
The sine-Gordon model in the presence of defects
Jean Avan, Anastasia Doikou
The sine-Gordon model in the presence of dynamical integrable defects is investigated. This is an application of the algebraic formulation introduced for integrable defects in earl…
The sine-Gordon model with integrable defects revisited
Jean Avan, Anastasia Doikou
Application of our algebraic approach to Liouville integrable defects is proposed for the sine-Gordon model. Integrability of the model is ensured by the underlying classical r-mat…
Liouville integrable defects: the non-linear Schrodinger paradigm
Jean Avan, Anastasia Doikou
A systematic approach to Liouville integrable defects is proposed, based on an underlying Poisson algebraic structure. The non-linear Schrodinger model in the presence of a single…
Integrable quantum spin chains and their classical continuous counterparts
Jean Avan, Anastasia Doikou, Konstadinos Sfetsos
We present certain classical continuum long wave-length limits of prototype integrable quantum spin chains, and define the corresponding construction of classical continuum Lax ope…
Systematic classical continuum limits of integrable spin chains and emerging novel dualities
Jean Avan, Anastasia Doikou, Konstadinos Sfetsos
We examine certain classical continuum long wave-length limits of prototype integrable quantum spin chains. We define the corresponding construction of classical continuum Lax oper…
