Exact solution of new integrable nineteen-vertex models and quantum spin-1 chains
A. Klümper, S. I. Matveenko, J. Zittartz
New exactly solvable nineteen vertex models and related quantum spin-1 chains are solved. Partition functions, excitation energies, correlation lengths, and critical exponents are…
Exact Groundstates for Antiferromagnetic Spin-One Chains with Nearest and Next-Nearest Neighbour Interactions
C. Lange, A. Klümper, J. Zittartz
We have found the exact ground state for a large class of antiferromagnetic spin-one chains with nearest and next-nearest neighbour interactions. The ground state is characterized…
Critical exponents of a multicomponent anisotropic t-J model in one dimension
R. Z. Bariev, A. Klümper, A. Schadschneider +1
A recently presented anisotropic generalization of the multicomponent supersymmetric model in one dimension is investigated. This model of fermions with general spin- is s…
Exact solution of a one-dimensional fermion model with interchain tunneling
R. Z. Bariev, A. Klümper, A. Schadschneider +1
A fermion model consisting of two chains with interchain tunneling is formulated and solved exactly by the Bethe ansatz method. The interchain tunneling leads to Cooper pair like b…
