摘要：

By using the so-called matrix-product ground state approach, a few one-dimensional quantum systems, including a frustrated spin-1/2 Heisenberg ladder, the ferromagnetic t-J-V model at half-filling, the antiferromagnetic J(z)-V model at 2/3 filling and the antiferromagnetic t-J(z)-V model at half-filling, are solved exactly. The correlation functions in the ground states are calculated. Some relevant results are also discussed.
