The SU(n) invariant massive Thirring model with boundary reflection
T. Kojima
We study the SU(n) invariant massive Thirring model with boundary reflection. Our approach is based on the free field approach. We construct the free field realizations of the boun…
Finite XXZ critical chain with double boundaries
T. Kojima
Finite XXZ chain with double boundaries is considered at critical regime . We construct the eigenvectors of finite Hamiltonian by means of vertex operators and the quasi-bo…
The massless XXZ chain with a boundary
T. Kojima
We study the XXZ chain with a boundary at massless regime . We give the free field realizations of the boundary vacuum state and it's dual. Using these realizations, we giv…
The 19-Vertex Model at critical regime
T. Kojima
We study the 19-vertex model associated with the quantum group at critical regime . We give the realizations of the type-I vertex operators in terms of fre…
The critical chain
T. Kojima, S. Yamasita
We study the spin chain at the critical regime . We give the free boson realizations of the type-I vertex operators and their duals. Using these free boson r…
Difference equations for the higher rank XXZ model with a boundary
T. Kojima, Y. -H. Quano
The higher rank analogue of the XXZ model with a boundary is considered on the basis of the vertex operator approach. We derive difference equations of the quantum Knizhnik-Zamolod…
