We study translation-invariant Gibbs measures for the Blume–Capel model with wand on a Cayley tree of order k. We find the exact critical value 𝜃cr = 1 such that, for 𝜃 ≥ 𝜃cr , there exists a unique translation-invariant Gibbs measure and, for 0 < 𝜃 < 𝜃cr , there are exactly three translation-invariant Gibbs measures in the presence of a wand in the analyzed model. In addition, we study the problem of (no) extremes for these measures.

在Cayley树上放弃的Blume-Capel模型的平移不变极端Gibbs测度
我们研究k阶Cayley树上带有魔杖的Blume-Capel模型的平移Gibbs测度。我们发现精确的临界值𝜃 cr = 1,使得对于𝜃≥𝜃 cr,存在一个唯一的平移不变吉布斯测度;对于0 <𝜃 <𝜃 cr,存在三个正变不变式Gibbs测度分析模型中的魔杖 另外,我们研究了这些措施的极端问题。
