The sl(N) twisted Yangian: bulk-boundary scattering & defects
Jean Avan, Anastasia Doikou, Nikos Karaiskos
We consider the sl(N) twisted Yangian quantum spin chain. In particular, we study the bulk and boundary scattering of the model via the solution of the Bethe ansatz equations in th…
Bethe Ansatz solution of the small polaron with nondiagonal boundary terms
Nikos Karaiskos, André M. Grabinski, Holger Frahm
The small polaron with generic, nondiagonal boundary terms is investigated within the framework of quantum integrability. The fusion hierarchy of the transfer matrices and its trun…
Transmission amplitudes from Bethe ansatz equations
Anastasia Doikou, Nikos Karaiskos
We consider the Heisenberg spin chain in the presence of integrable spin defects. Using the Bethe ansatz methodology, we extract the associated transmission amplitudes, that descri…
Junction type representations of the Temperley-Lieb algebra and associated symmetries
Anastasia Doikou, Nikos Karaiskos
Inspired by earlier works on representations of the Temperley-Lieb algebra we introduce a novel family of representations of the algebra. This may be seen as a generalization of th…
Introduction to Quantum Integrability
Anastasia Doikou, Stefano Evangelisti, Giovanni Feverati +1
In this article we review the basic concepts regarding quantum integrability. Special emphasis is given on the algebraic content of integrable models. The associated algebras are e…
New reflection matrices for the U_q(gl(m|n)) case
Anastasia Doikou, Nikos Karaiskos
We examine super symmetric representations of the B-type Hecke algebra. We exploit such representations to obtain new non-diagonal solutions of the reflection equation associated t…
