复曲面蜂窝晶格中的任意子模型

An anyon model in a toric honeycomb lattice

Long Liang, Yue Yu

摘要:

研究了复曲面蜂窝晶格中的任意子模型。其基态和低激发态与Kitaev环码模型的基态和低激发态一致,符合互半离子统计。该模型有助于以更对称的方式理解任意子的环面码。另一方面,通过Jordan-Wigner变换,这种复曲面蜂窝模型与正方形晶格中的边界耦合伊辛链阵列之间有直接的联系。我们讨论了这两种模型在低层区的等价性,并在一个常规的费米子系统中实现了这些任意子的激发。

英文摘要:

We study an anyon model in a toric honeycomb lattice. The ground states and the low-lying excitations coincide with those of Kitaev toric code model and then the excitations obey mutual semionic statistics. This model is helpful to understand the toric code of anyons in a more symmetric way. On the other hand, there is a direct relation between this toric honeycomb model and a boundary coupled Ising chain array in a square lattice via Jordan-Wigner transformation. We discuss the equivalence between these two models in the low-lying sector and realize these anyon excitations in a conventional fermion system.
