广义Ising树

Generic Ising Trees

Bergfinnur Durhuus, George M. Napolitano

摘要:

无限泛树上的伊辛模型被定义为有限系统的热力学极限。给出了相应的无限自旋组态分布的详细描述。作为应用,我们研究了这类系统的磁化性质,证明了它们不具有自发磁化。此外,计算了底层树的Hausdorff维数和谱维数的值,发现分别为$\bar{d}_h=2$和$\bar{d}_s=4/3$。

英文摘要:

The Ising model on an infinite generic tree is defined as a thermodynamic limit of finite systems. A detailed description of the corresponding distribution of infinite spin configurations is given. As an application we study the magnetization properties of such systems and prove that they exhibit no spontaneous magnetization. Furthermore, the values of the Hausdorff and spectral dimensions of the underlying trees are calculated and found to be, respectively, $\bar{d}_h=2$ and $\bar{d}_s=4/3$.
