Geometry of reduced density matrices for symmetry-protected topological phases

Ji-Yao Chen, Zhengfeng Ji, Zheng-Xin Liu +2

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…

Symmetry protected topological phases in spin-1 ladders and their phase transitions

Ji-Yao Chen, Zheng-Xin Liu

We study two-legged spin-1 ladder systems with $D_{2} \times σ$ symmetry group, where $D_{2}$ is discrete spin rotational symmetry and $σ$ means interchain reflection symmetry. The syst…
