论文摘要
我们描述了一项方案，以读取相互作用的1D手性模型的拓扑不变，以测量随时间不断发展的散装激发的平均手性位移。我们介绍了相互作用的Su-Schrieffer-Heeger（SSH）链的分析计算和数值矩阵乘积模拟，证明了平均手性位移如何允许如何区分拓扑绝缘子，琐碎的绝缘子和对称性旋转相。最后，我们提供了一个实验性蓝图，用于实现显示这三个阶段的模型，并描述如何检测这些阶段。
We describe a protocol to read out the topological invariant of interacting 1D chiral models, based on measuring the mean chiral displacement of time-evolving bulk excitations. We present analytical calculations and numerical Matrix Product State simulations of interacting Su-Schrieffer-Heeger (SSH) chains, demonstrating how the mean chiral displacement allows to distinguish between topological insulator, trivial insulator and symmetry-broken phases. Finally, we provide an experimental blueprint for realizing a model displaying these three phases and describe how to detect those.
