论文摘要
我们提出了一个有效的方案，用于基于音调晶体中的硅离散（SIV）中心阵列模拟物质的拓扑阶段。这种语音带隙结构允许与可调轮廓进行远距离自旋相互作用。在特定的周期性微波驾驶下，可以通过Su-Schrieffer-Heeger（SSH）Hamiltonian的形式进一步设计带隙介导的自旋旋转相互作用。在动量空间中，我们研究了SSH模型的拓扑特征，并表明可以通过调节周期性驾驶场来获得拓扑非平凡相。此外，我们探索了颜色中心阵列边界处的零能量拓扑边缘状态，并研究通过拓扑边缘状态的稳健量子信息传输。该设置为研究拓扑量子物理学和量子信息处理提供了一个可扩展且有希望的平台，并使用颜色中心和声音晶体进行处理。
We propose an efficient scheme for simulating the topological phases of matter based on silicon-vacancy (SiV) center arrays in phononic crystals. This phononic band gap structure allows for long-range spin-spin interactions with a tunable profile. Under a particular periodic microwave driving, the band-gap mediated spin-spin interaction can be further designed with the form of the Su-Schrieffer-Heeger (SSH) Hamiltonian. In momentum space, we investigate the topological characters of the SSH model, and show that the topological nontrivial phase can be obtained through modulating the periodic driving fields. Furthermore, we explore the zero-energy topological edge states at the boundary of the color center arrays, and study the robust quantum information transfer via the topological edge states. This setup provides a scalable and promising platform for studying topological quantum physics and quantum information processing with color centers and phononic crystals.
