超导宇宙弦与一维广义超对称代数

Superconducting Cosmic Strings and One Dimensional Extended Supersymmetric Algebras

V. K. Oikonomou

摘要:

在这篇文章中,我们详细研究了超导宇宙弦周围的费米零模系统的超对称结构。特别地,我们扩展了文献中关于一维$N=2$超对称性的分析,发现了多重$N=2$,$d=1$超对称性.此外,紧扰动的Witten指数的系统进行,我们发现这些扰动对应的物理情况。更重要的是,我们证明了在具有$N_f$味的费米子系统中存在着更丰富的超对称结构,这些结构是具有非平凡拓扑荷的$N$ -扩展超对称结构,其中“$N$“依赖于费米子味.

英文摘要:

In this article we study in detail the supersymmetric structures that underlie the system of fermionic zero modes around a superconducting cosmic string. Particularly, we extend the analysis existing in the literature on the one dimensional $N=2$ supersymmetry and we find multiple $N=2$, $d=1$ supersymmetries. In addition, compact perturbations of the Witten index of the system are performed and we find to which physical situations these perturbations correspond. More importantly, we demonstrate that there exists a much more rich supersymmetric structure underlying the system of fermions with $N_f$ flavors and these are $N$-extended supersymmetric structures with non-trivial topological charges, with "$N$" depending on the fermion flavors.
