"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…

Parity and Charge Conjugation Symmetries and S Matrix of the XXZ Chain

Anastasia Doikou, Rafael I. Nepomechie

We formulate the notion of parity for the periodic XXZ spin chain within the Quantum Inverse Scattering Method. We also propose an expression for the eigenvalues of the charge conj…
