Integrability as a consequence of discrete holomorphicity: loop models

I T Alam, M T Batchelor

摘要:

在Potts稠密圈模型和O(n)稀疏圈模型下,研究了一类复晶格观测量的离散全纯性与可积性之间的关系.结果表明,可积性的条件,即反演和杨巴克斯特关系,可以从全纯的条件的观测。此外,Z-不变性的模型示出,在其平面菱形嵌入的菱形的重排下的子晶格的边界上的可观测量的不变性。

英文摘要:

In this paper, we explore the relationship between integrability and the discrete holomorphicity of a class of complex lattice observables in the context of the Potts dense loop model and the O(n) dilute loop model. It is shown that the conditions for integrability, namely, the inversion and Yang-Baxter relations, can be derived from the condition of holomorphicity of the observables. Furthermore, the Z-invariance of the models is shown to result in the invariance of the observables on the boundary of a sublattice under reshuffling of the rhombuses of its planar rhombic embedding.
