M. Assis, J. L. Jacobsen, I. Jensen, J-M. Maillard, B. M. McCoy

摘要:

通过计算有限大系统的零点和转移矩阵特征值,研究了复逸度平面上硬六边形模型的配分函数的解析性。我们发现,配分函数每个网站计算巴克斯特在热力学极限的正实值的逸度是不足以描述在全复逸度平面的解析性。我们还得到了一个新的代数方程的低密度配分函数每网站。

英文摘要:

We study the analyticity of the partition function of the hard hexagon model in the complex fugacity plane by computing zeros and transfer matrix eigenvalues for large finite size systems. We find that the partition function per site computed by Baxter in the thermodynamic limit for positive real values of the fugacity is not sufficient to describe the analyticity in the full complex fugacity plane. We also obtain a new algebraic equation for the low density partition function per site.
