摘要：

We examine a quantum-spin-glass model with a transverse field. The network is based on a modified version of the Hopfield spin glass. A set of equations for the order parameters describing the ordered phases are obtained, and the effects of the quantum fluctuations and the stored patterns on the phase transitions between the ordered phases are examined. We see that reentry occurring in the mixed-phase transitions can be observed in the present system.
