论文摘要
我们提出了一个由Blume-Emery-Griffiths（BEG）Hamiltonian和平均田间相互作用的混合模型，其中旋转被随机淬火，以使其中一些是“纯粹的” Ising，而另一些则承认了Beg的状态。通过改变Ising旋转的浓度，该模型在规范和微炮弹集合中显示了浓度 - 温度参数空间中的不同相肖像。这些肖像丰富且相当不寻常的现象学迹象。
We propose a hybrid model governed by the Blume-Emery-Griffiths (BEG) Hamiltonian with a mean-field-like interaction, where the spins are randomly quenched such that some of them are "pure" Ising and the others admit the BEG set of states. It is found, by varying the concentration of the Ising spins, that the model displays different phase portraits in concentration-temperature parameter space, within the canonical and the microcanonical ensembles. Phenomenological indications that these portraits are rich and rather unusual are provided.
