等径图上的Ashkin-Teller模型

Ashkin-Teller model on the iso-radial graphs

S. Lottini, M. A. Rajabpour

摘要:

利用正方形格子上各向异性Ashkin-Teller模型的结果,我们找到了一般等径图上Ashkin-Teller模型的临界面。不同的几何方面,这个关键的表面进行了讨论,特别是它们的连接各向异性角。利用反演恒等式提取了模型在一般等径图上的自由能。此外,还讨论了临界线上某些特殊点处的格全纯变量。本文对各向异性三角格子Ashkin-Teller模型进行了数值计算。

英文摘要:

We find the critical surface of the Ashkin-Teller model on the generic iso-radial graphs by using the results for the anisotropic Ashkin-teller model on the square lattice. Different geometrical aspects of this critical surface are discussed, especially their connection to the anisotropy angle. The free energy of the model on the generic iso-radial graph is extracted using the inversion identities. In addition, lattice holomorphic variables are discussed at some particular points of the critical line. We check our conjectures numerically for the anisotropic triangular-lattice Ashkin-Teller model.
