Ising spin glasses in a transverse field exhibit a zero temperature quantum phase transition, which is driven by quantum rather than thermal fluctuations. They constitute a universality class that is significantly different from the classical, thermal phase transitions. Most interestingly close to the transition in finite dimensions a quantum Griffiths phase leads to drastic consequences for various physical quantities: for instance diverging magnetic susceptibilities are observable over a whole range of transverse field values in the disordered phase.

    The finite temperature features of this model are more delicate because of the issue of replica symmetry breaking. See Y. Y. Goldschmidt and P. Y. Lai, Phys. Rev. Lett. 64, 2567 (1990) and B. K.
