摘要：

We examine the quantum phase transition at zero temperature between paramagnetic and spin-glass-ordered phases as the strength of a uniform transverse field, GAMMA, is varied. At the critical point, GAMMA(c), the spin autocorrelation function decays with time, t, as t-2 . As the transition is- approached from the paramagnetic phase the nonlinear susceptibility diverges as {\ln(GAMMA-GAMMA(c))\/(GAMMA-GAMMA(c))}1/2.
