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…
Non-Abelian anyons: inversion identities for higher rank face models
Holger Frahm, Nikos Karaiskos
The spectral problem for an integrable system of particles satisfying the fusion rules of is expressed in terms of exact inversion identities satisfied by the commuting t…
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…
Inversion identities for inhomogeneous face models
Holger Frahm, Nikos Karaiskos
We derive exact inversion identities satisfied by the transfer matrix of inhomogeneous interaction-round-a-face (IRF) models with arbitrary boundary conditions using the underlying…
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…
