某些周期性驱动的量子多粒子系统在一维中表现出与拓扑性质相关的边缘模式，并导致Floquet谱的近似简并。类似的情况也发生在自旋链中，在某些可积自旋链中，稳定的边缘模式在所有能量下都存在。此外，这些边缘模式被发现是非常稳定的扰动。在这里，我们调查的边缘模式的稳定性相互作用，周期性驱动，清洁系统。我们引入了一个模型，其特征在于边缘模式，持续超过时标，远远超过系统的大部分加热到无限温度所需的时间。
Certain periodically driven quantum many-particle systems in one dimension are known to exhibit edge modes that are related to topological properties and lead to approximate degeneracies of the Floquet spectrum. A similar situation occurs in spin chains, where stable edge modes were shown to exist at all energies in certain integrable spin chains. Moreover, these edge modes were found to be remarkably stable to perturbations. Here we investigate the stability of edge modes in interacting, periodically driven, clean systems. We introduce a model that features edge modes that persist over timesscales well in excess of the time needed for the bulk of the system to heat to infinite temperatures.
