摘要:

寻找格算子和描述其长距离性质的连续场之间的精确对应对于强相互作用临界点来说是一个很大程度上开放的问题。在这里,我们基本上完全解决了这个问题的情况下,三态波茨模型,表现出一个强相互作用的“parafermion”共形场论描述的相变。使用对称性参数,从可积性的见解,和广泛的模拟,我们构建晶格模拟几乎所有的相关和边缘的物理领域管理这个过渡。这种结构包括手征场,如顺费米子。一路上,我们还澄清了结构的算子乘积展开之间的秩序和混乱的领域,我们确认数字。我们的研究结果都提出了一个系统的方法来攻击非自由场论的晶格,并找到更广泛的应用在追求异国情调的拓扑有序相的物质。

英文摘要:

Finding the precise correspondence between lattice operators and the continuum fields that describe their long-distance properties is a largely open problem for strongly interacting critical points. Here we solve this problem essentially completely in the case of the three-state Potts model, which exhibits a phase transition described by a strongly interacting 'parafermion' conformal field theory. Using symmetry arguments, insights from integrability, and extensive simulations, we construct lattice analogues of nearly all the relevant and marginal physical fields governing this transition. This construction includes chiral fields such as the parafermion. Along the way we also clarify the structure of operator product expansions between order and disorder fields, which we confirm numerically. Our results both suggest a systematic methodology for attacking non-free field theories on the lattice and find broader applications in the pursuit of exotic topologically ordered phases of matter.
