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…

Sigma models in the presence of dynamical point-like defects
Anastasia Doikou, Nikos Karaiskos
Point-like Liouville integrable dynamical defects are introduced in the context of the Landau-Lifshitz and Principal Chiral (Faddeev-Reshetikhin) models. Based primarily on the und…
