格点上的一类非阿贝尔Kitaev模型:拓扑约束与凝聚

A Family of Non-Abelian Kitaev Models on a Lattice: Topological Confinement and Condensation

H. Bombin, M. A. Martin-Delgado

摘要:

我们研究了一个家庭的非阿贝尔拓扑模型中出现的晶格修改Kitaev模型通过引入单qudit条款。这些项的影响相当于相对于原始系统的离散规范对称性的减少,这对应于显式对称性破缺的广义机制。在各种模型中,拓扑顺序要么部分丢失,要么完全被破坏。新的系统显示凝聚和限制的拓扑电荷存在于标准的非阿贝尔Kitaev模型,我们研究的带状算子代数。

英文摘要:

We study a family of non-Abelian topological models in a lattice that arise by modifying the Kitaev model through the introduction of single-qudit terms. The effect of these terms amounts to a reduction of the discrete gauge symmetry with respect to the original systems, which corresponds to a generalized mechanism of explicit symmetry breaking. The topological order is either partially lost or completely destroyed throughout the various models. The new systems display condensation and confinement of the topological charges present in the standard non-Abelian Kitaev models, which we study in terms of ribbon operator algebras.
