L. Chao et al., BOSONIC REALIZATION OF BOUNDARY OPERATORS IN SU(2)-INVARIANT THIRRINGMODEL, International journal of modern physics A, 10(31), 1995, pp. 4469-4482
Boundary operators and boundary states in the SU(2)-invariant Thirring
model are considered from the point of view of bosonization and oscil
lator realizations of bulk and boundary Zamolodchikov-Faddeev algebras
