Phys. Rev. B 34, 1677–1682 (1986)Correlation functions of the antiferromagnetic Heisenberg model using a modified Lanczos methodSee Also: Erratum Received 30 January 1986; published in the issue dated 1 August 1986 Using a modified Lanczos algorithm, we study the correlation functions in the ground state of the one-dimensional antiferromagnetic Heisenberg model. We obtain numerical results for rings up to 24 sites. There are no indications of the anomalous behavior of these correlation functions recently observed in chains with 16 sites. We also present a pedagogical description of the hashing technique which is an efficient algorithm for searching and storage purposes. © 1986 The American Physical Society URL:
