一维Aubry-André模型边缘态的动力学特征

Dynamical signature of edge state in the 1D Aubry-André model

H. Z. Shen, X. X. Yi, C. H. Oh

摘要:

拓扑特征已成为物理学许多领域的研究热点。作为拓扑相位的见证,边缘态得到了拓扑保护,并可能有助于量子信息处理。本文定义了一种度量系统动力学局域化的测度,并在一维Aubry-André模型中模拟了系统的动力学局域化。我们发现边态和系统的动力学局域化之间存在一种有趣的联系,这种联系可以作为边态和拓扑相的一种标志。

英文摘要:

Topological feature has become an intensively studied subject in many fields of physics. As a witness of topological phase, the edge states are topologically protected and may be helpful in quantum information processing. In this paper, we define a measure to quantify the dynamical localization of system and simulate the localization in the 1D Aubry-André model. We find an interesting connection between the edge states and the dynamical localization of the system, this connection may be used as a signature of edge state and topological phase.
