Kitaev量子双晶格模型到Levin和Wen弦网模型的映射

Mapping Kitaev's quantum double lattice models to Levin and Wen's string-net models

Oliver Buerschaper, Miguel Aguado

摘要:

我们展示了一个映射识别Kitaev的量子双晶格模型明确作为一个子类的莱文和温的弦网络模型通过完成本地希尔伯特空间与辅助自由度。这种识别允许携带到这些弦网络模型中的量子双模型中的激发的表示论分类,以及在任意晶格中定义它们,并提供了森田等价的抽象概念的说明。广义映射到更广泛的类弦网的可能性被认为是。

英文摘要:

We exhibit a mapping identifying Kitaev's quantum double lattice models explicitly as a subclass of Levin and Wen's string net models via a completion of the local Hilbert spaces with auxiliary degrees of freedom. This identification allows to carry over to these string net models the representation-theoretic classification of the excitations in quantum double models, as well as define them in arbitrary lattices, and provides an illustration of the abstract notion of Morita equivalence. The possibility of generalising the map to broader classes of string nets is considered.
