Extracting topological information from momentum space propagators

Fabrizio Canfora, David Dudal, Alex Giacomini, Igor F. Justo, Pablo Pais, Luigi Rosa

摘要:

提出了一个新的拓扑不变量,它对费米子和玻色子传播子的解析结构都敏感。我们构造的规范不变性至少对小规范变换是有保证的。一个广义兼容的存在下,复杂的极点的介绍和适用于传播的分类通常出现从非微扰的考虑。我们提出的部分证据表明,拓扑数可以用来检测手征对称性破缺或解除禁闭。

英文摘要:

A new topological invariant quantity, sensitive to the analytic structure of both fermionic and bosonic propagators, is proposed. The gauge invariance of our construct is guaranteed for at least small gauge transformations. A generalization compatible with the presence of complex poles is introduced and applied to the classification of propagators typically emerging from non-perturbative considerations. We present partial evidence that the topological number can be used to detect chiral symmetry breaking or deconfinement.
