一个规范不变的三维对偶角面伊辛模型

A Gauge Invariant Dual Gonihedric 3D Ising Model

D. A. Johnston, R. P. K. C. M. Ranasinghe

摘要:

我们注意到,两个配方的对偶角面伊辛模型在3D中,一个基于使用韦格纳的一般框架的对偶构造一个对偶哈密顿余维一个表面,另一个构造一个对偶哈密顿二维表面,是相关的标准装饰/迭代变换的变体。二维表面的对偶哈密顿量包含链接和顶点自旋的混合,因此具有规范不变性,这是由余维一表面哈密顿量继承。这种规范不变性确保了后者等价于第三个公式,即各向异性的Ashkin-Teller模型。我们详细描述了等价性,并讨论了一些支持这些意见的蒙特卡罗模拟。

英文摘要:

We note that two formulations of dual gonihedric Ising models in 3d, one based on using Wegner's general framework for duality to construct a dual Hamiltonian for codimension one surfaces, the other on constructing a dual Hamiltonian for two-dimensional surfaces, are related by a variant of the standard decoration/iteration transformation. The dual Hamiltonian for two-dimensional surfaces contains a mixture of link and vertex spins and as a consequence possesses a gauge invariance which is inherited by the codimension one surface Hamiltonian. This gauge invariance ensures the latter is equivalent to a third formulation, an anisotropic Ashkin-Teller model. We describe the equivalences in detail and discuss some Monte-Carlo simulations which support these observations.
