总自旋量子数严格计算的量子版本的马蒂斯模型的随机自旋系统。在存在随机性的情况下，明确地给出了伊辛模型、XY模型和海森堡模型三个普适类之间的交叉。Mattis模型的随机性即使在量子系统中也没有热力学效应。
Total spin quantum number is rigorously calculated for a quantum version of the Mattis model of random spin systems. Crossover between three universality classes of the Ising model, theXYmodel, and the Heisenberg model is explicitly worked out in the presence of randomness. The randomness of the type of the Mattis model is shown to have no thermodynamic effects even in quantum systems.
