摘要:
The t - J model (related to the strong-correlation limit of the Hubbard model) is shown to be soluble in one dimension using the Bethe ansatz. The solution holds only when the Hamiltonian is supersymmetric. The ground state in the presence of holes is found to be gapless, and to have no magnetization.
