Y R Kartik, Rahul S, Ranjith Kumar R, Sujit Sarkar

摘要:

本文研究并给出了量子物质拓扑态的Berry联系。Berry连接在量子多体系统的几何相位和拓扑现象中起着核心作用。通过复分析给出了刻画系统拓扑性质的充分必要条件。我们还提出了不同的拓扑方面的系统在动量空间。

英文摘要:

We study and present the results of Berry connection for the topological states in quantum matter. The Berry connection plays a central role in the geometric phase and topological phenomenon in quantum many-body system. We present the necessary and sufficient conditions to characterize the topological nature of the system through the complex analysis. We also present the different topological aspects of the system in the momentum space.
