一维拓扑交换统计量

Topological Exchange Statistics in One Dimension

N. L. Harshman, A. C. Knapp

摘要:

标准的拓扑方法,以不可区分的粒子制定交换统计使用的基本群分析的连通性的配置空间。虽然在二维和多维中是成功的,但这种方法在一维中只给出平凡或接近平凡的交换统计,因为两体符合被排除在配置空间之外。相反,我们包括这些路径模糊的奇点,并考虑配置空间作为一个orbifold。这种orbifold拓扑方法允许在任何维度上统一分析交换统计,并预测一维系统中任意子的新可能性,包括服从交替链群的非阿贝尔任意子。这些结果澄清了一维任意子模型中分数统计的非拓扑起源。

英文摘要:

The standard topological approach to indistinguishable particles formulates exchange statistics by using the fundamental group to analyze the connectedness of the configuration space. Although successful in two and more dimensions, this approach gives only trivial or near trivial exchange statistics in one dimension because two-body coincidences are excluded from configuration space. Instead, we include these path-ambiguous singular points and consider configuration space as an orbifold. This orbifold topological approach allows unified analysis of exchange statistics in any dimension and predicts novel possibilities for anyons in one-dimensional systems, including non-abelian anyons obeying alternate strand groups. These results clarify the non-topological origin of fractional statistics in one-dimensional anyon models.
