Principal chiral model scattering and the alternating quantum spin chain
Anastasia Doikou, Andrei Babichenko
We consider the critical alternating quantum spin chain with , spins. Using the Bethe ansatz technique we find explicit expressions for the -mat…

"New" boundary conditions in integrable lattice models
Anastasia Doikou
We consider the case of an integrable quantum spin chain with ``soliton non-preserving'' boundary conditions. This is the first time that such boundary conditions have been conside…
