讨论了自旋玻璃和其他无序体系中存在多个纯态的问题。作者表明，重叠的分布，P（q），是一个不可靠的指标有多少不同的纯态系统。他们讨论了纯态的定义和纯态之间可能的关系。他们还讨论了Bethe晶格上的自旋玻璃和无限程模型，指出为什么它们的有序相可能与现实的自旋玻璃模型不同。有限范围的自旋玻璃的行为的各种可能性进行了讨论。
The question of the existence of multiple pure states in spin glasses and other disordered systems is considered. The authors show that the distribution of overlaps, P(q), is an unreliable indicator of how many distinct pure states a system has. They discuss the definition of, and possible relations between, pure states. They also discuss the spin glass on a Bethe lattice and the infinite-range model, pointing out why their ordered phases are likely to be unlike that of realistic spin glass models. Various possibilities for the behaviour of finite-range spin glasses are discussed.
