拓扑有序相态:从结和辫到量子二聚体

Topologically ordered phase states: from knots and braids to quantum dimers

Luigi Martina, Alexander Protogenov, Valery Verbus

摘要:

我们考虑系统的普遍统计性质,其特征在于与宏观简并的基态的相态。在这样的系统中的一个可能的拓扑顺序由非线性离散方程描述。我们专注于广义不相容原理统计的情况下发生的离散方程。证明了它们的精确解是某个量子群的不可约表示的量子维数。这些解提供了广义不相容原理统计量和辫子统计量相遇的一个例子。我们提出了一种利用一维拓扑结构的编织特征的打结场组态的投影来构造量子二聚体模型的方法。

英文摘要:

We consider universal statistical properties of systems that are characterized by phase states with macroscopic degeneracy of the ground state. A possible topological order in such systems is described by non-linear discrete equations. We focus on the discrete equations which take place in the case of generalized exclusion principle statistics. We show that their exact solutions are quantum dimensions of the irreducible representations of certain quantum group. These solutions provide an example of the point where the generalized exclusion principle statistics and braid statistics meet each other. We propose a procedure to construct the quantum dimer models by means of projection of the knotted field configurations that involved braiding features of one-dimensional topology.
