Description:
Author(s): Ji-Yao Chen, Zhengfeng Ji, Zheng-Xin Liu, Yi Shen, and Bei Zeng In this paper, we study the geometry of reduced density matrices for states with symmetry-protected topological (SPT) order. We observe ruled surface structures on the boundary of the convex set of low-dimensional projections of the reduced density matrices. In order to signal the SPT order using ru… [Phys. Rev.
