Quantum spin glasses with uniaxial exchange anisotropy

A long-range quantum spin glass model with uniaxial exchange anisotropy is studied using the replica method. The phase diagrams are derived for spin quantum numbers S = 1 2 , 1, 3 2 and are observed to be qualitatively very similar to the results of the classical vector spin model.
