M. Anda, E. Fuenmayor, L. Leal, E. Contreras

AI总结:

本文微扰分析非Abel Chern-Simons-Wong模型,显式构造出仅依赖闭合曲线的二阶在壳作用量作为链环不变量解析式,并构建重现该作用量的Abel中间模型,证明此拓扑不变量能有效检测四分量链环的纽结。

摘要:

在这项工作中,我们对拓扑非Abel Chern-Simons-Wong模型进行微扰分析,旨在显式构造二阶在壳作用量。所得作用量是一个仅依赖于闭合曲线的拓扑量,因此对应于链环不变量的解析表达式。此外,我们构造了一个Abel模型,它重现了与其非Abel Chern-Simons-Wong对应物相同的二阶在壳作用量,从而作为中间模型,其特征是由闭合路径上的电流生成的Abel场。通过对各项进行几何分析,我们证明该拓扑不变量能有效检测四分量链环的纽结。

英文摘要:

In this work, we undertake a perturbative analysis of the topological non-Abelian Chern-Simons-Wong model with the aim to explicitly construct the second-order on-shell action. The resulting action is a topological quantity depending solely on closed curves, so it correspond to an analytical expression of a link invariant. Additionally, we construct an Abelian model that reproduces the same second-order on-shell action as its non-Abelian Chern-Simons-Wong counterpart so it functions as an intermediate model, featuring Abelian fields generated by currents supported on closed paths. By geometrically analyzing each term, we demonstrate that this topological invariant effectively detects the knotting of a four-component link.
