Description:
Author(s): Tian Chen, Bo Wang, and Xiangdong Zhang We present a method to detect topological invariants in nonunitary parity-time-symmetric (PT-symmetric) quantum walks (QWs). The topological phases of a PT-symmetric QW can be characterized by the mean position of the walk, which is an experimentally observable quantity. This method can also be appl... [Phys. Rev.
