Phys. Rev. Lett. 43, 1434–1437 (1979)Random Antiferromagnetic ChainSee Also: Erratum Received 7 August 1979; published in the issue dated 5 November 1979 The quantum spin-½ Heisenberg antiferromagnet in one dimension with randomly distributed coupling constants is solved approximately. Ground-state energies and low-temperature properties are obtained for several distributions of coupling constants (including both singular and nonsingular distributions). Power-law temperature dependence in specific heat and in susceptibility are found for all distributions studied. © 1979 The American Physical Society URL:
