论文摘要
量子步行（QW）作为经典随机步行的量子类似物，为研究拓扑现象和非平衡动力学提供了可行的平台。在这里，我们提出了一种新颖的方案，以实现量子行走，其中fock状态提供步行空间和零声子状态$ \ left | n = 0 \ right \ rangle $作为其自然边界。因此，我们的计划提供了独特的机会来研究相应拓扑系统的界面状态的动态。特别是，可以通过调整散装参数和局部边界操作员来广泛研究结合状态的淬灭动力学，这是可以在实验上访问的。我们的建议不仅提供了一种新的方法来探索拓扑系统界面状态的特征，而且还提供了一种通过动态过程来确定不同阶段的方法。
The quantum walk (QW), as the quantum analog of classical random walk, provides a feasible platform to study the topological phenomenon and non-equilibrium dynamics. Here, we propose a novel scheme to realize the quantum walk with a single trapped ion where the Fock states provides the walk space and zero phonon state $\left|n=0\right\rangle $ serves as its natural boundary. Thus, our scheme offers the unique opportunity to investigate the dynamics of the bound states of the corresponding topological systems. Particularly, the quench dynamics of the bound states can be extensively studied by tuning the bulk parameters and the local boundary operator, which are experimentally accessible. Our proposal not only offers a new approach to exploring the character of the bound states of the topological systems, but also offers a way to determine different phases through the dynamical processes.
