Boundary Bound States in Affine Toda Field Theory
A. Fring, R. Koberle
We demonstrate that the generalization of the Coleman-Thun mechanism may be applied to the situation, when considering scattering processes in 1+1-dimensions in the presence of ref…
Affine Toda Field Theory in the Presence of Reflecting Boundaries
A. Fring, R. Köberle
We show that the ``boundary crossing-unitarity equation" recently proposed by Ghoshal and Zamolodchikov is a consequence of the boundary bootstrap equation for the S-matrix and the…
Factorized Scattering in the Presence of Reflecting Boundaries
A. Fring, R. Köberle
We formulate a general set of consistency requirements, which are expected to be satisfied by the scattering matrices in the presence of reflecting boundaries. In particular we der…
Exact solution of the deformed biquadratic spin 1 hamiltonian
R. Koberle, A. Lima - Santos
Remarks about highest weight states of the underlying quantum group are corrected.
