自旋驱动囚禁离子链中的拓扑边缘态

Topological edge states in periodically-driven trapped-ion chains

Pedro Nevado, Samuel Fernández-Lorenzo, Diego Porras

摘要:

拓扑绝缘相主要与凝聚态物质系统有关,通常具有短程相互作用。尽管如此,量子物质的许多实现可以表现出长程相互作用,而且这些长程相互作用对拓扑相的影响在很大程度上仍然未知。在这封信中,我们研究了存在长程相互作用的Su-Schrieffer-Heeger拓扑绝缘体。我们表明,这个模型可以很容易地实现在量子模拟器与捕获离子通过周期性的驱动。我们的研究结果表明,相关的边缘态的本地化增强的长程相互作用,本地化的组件生存的基态的模型。这些效果可以很容易地证实在目前的国家的最先进的实验实现。

英文摘要:

Topological insulating phases are primarily associated with condensed-matter systems, which typically feature short-range interactions. Nevertheless, many realizations of quantum matter can exhibit long-range interactions, and it is still largely unknown the effect that these latter may exert upon the topological phases. In this Letter, we investigate the Su-Schrieffer-Heeger topological insulator in the presence of long-range interactions. We show that this model can be readily realized in quantum simulators with trapped ions by means of a periodic driving. Our results indicate that the localization of the associated edge states is enhanced by the long-range interactions, and that the localized components survive within the ground state of the model. These effects could be easily confirmed in current state-of-the-art experimental implementations.
