Exact S-matrices with Affine Quantum Group Symmetry
نویسنده
چکیده
We show how to construct the exact factorized S-matrices of 1+1 dimensional quantum field theories whose symmetry charges generate a quantum affine algebra. Quantum affine Toda theories are examples of such theories. We take into account that the Lorentz spins of the symmetry charges determine the gradation of the quantum affine algebras. This gives the S-matrices a non-rigid pole structure. It dependson a kind of “quantum” dual Coxeter number which will therefore also determine the quantum mass ratios in these theories. As an example we explicitly construct S-matrices with Uq(c (1) n ) symmetry.

Quantum integrable models that possess N = 2 supersymmetry are investigated on the half-space. Conformal perturbation theory is used to identify some N = 2 supersymmetric boundary integrable models, and the effective boundary Landau-Ginzburg formulations are constructed. It is found that N = 2 supersymmetry largely determines the boundary action in terms of the bulk, and in particular, the boun...

We construct the family of spin chain Hamiltonians, which have affine quantum group symmetry U q ˆ g. Their eigenvalues coincide with the eigen-values of the usual spin chain Hamiltonians, but have the degeneracy of levels, corresponding to affine U q ˆ g. The space of states of these spin chains is formed by the tensor product of fully reducible representations of quantum group. The fermionic ...

متن کاملExact quantum S-matrices for solitons in simply-laced affine Toda field theories
We obtain exact solutions to the quantum S-matrices for solitons in simply-laced affine Toda field theories, except for certain factors of simple type which remain undetermined in some cases. These are found by postulating solutions which are consistent with the semi-classical limit, h̄ → 0, and the known time delays for a classical two soliton interaction. This is done by a ‘q-deformation’ proc...
