AI总结:

本文研究了非阿贝尔任何子气体的多体谱理论,通过非阿贝尔表示和无限多strand的braid群表示,推导了交换算子和相位,并扩展了统计排斥方法到任意几何任何子模型。

摘要:

我们回顾并发展了理想任何子的多体谱理论,即平面内相同量子粒子的交换规则由braid群N strand的单位表示支配。允许任意秩(依赖于N)和非阿贝尔表示,并让N趋于无穷,这定义了理想非阿贝尔多任何子气体。我们计算了由融合代数定义的一类广泛表示中的交换算子和相位,包括Fibonacci和Ising任何子模型。此外,我们将为阿贝尔任何子发展的方法扩展到任意几何任何子模型,即任意单位表示序列的braid群,其中两任何子交换非平凡。

英文摘要:

We review and develop the many-body spectral theory of ideal anyons, i.e. identical quantum particles in the plane whose exchange rules are governed by unitary representations of the braid group on $N$ strands. Allowing for arbitrary rank (dependent on $N$) and non-abelian representations, and letting $N \to \infty$, this defines the ideal non-abelian many-anyon gas. We compute exchange operators and phases for a common and wide class of representations defined by fusion algebras, including the Fibonacci and Ising anyon models. Furthermore, we extend methods of statistical repulsion (Poincaré and Hardy inequalities) and a local exclusion principle (also implying a Lieb-Thirring inequality) developed for abelian anyons to arbitrary geometric anyon models, i.e. arbitrary sequences of unitary representations of the braid group, for which two-anyon exchange is nontrivial.
