基于格林函数的强关联拓扑超导体和拓扑相变

Strongly Correlated Topological Superconductors and Topological Phase Transitions via Green's Function

Zhong Wang, Shou-Cheng Zhang

摘要:

本文提出了几个拓扑超导体的拓扑序参量,它们用零频格林函数表示,推广了前人对相互作用绝缘体的工作.拓扑场论中的系数用零频格林函数表示。我们还研究了在零频率格林函数方法中超越非相互作用极限的拓扑相变。

英文摘要:

We propose several topological order parameters expressed in terms of Green's function at zero frequency for topological superconductors, which generalizes the previous work for interacting insulators. The coefficient in topological field theory is expressed in terms of zero frequency Green's function. We also study topological phase transition beyond noninteracting limit in this zero frequency Green's function approach.
