Classification of Average Crystalline Topological Superconductors through a Generalized Real-Space Construction
Sarvesh Srinivasan, Jian-Hao Zhang, Yang Qi +1
We investigate a novel class of topological superconducting phases protected by exact fermion-parity symmetry and average crystalline symmetries. These phases belong to the broader…

Locally Purified Density Operators for Symmetry-Protected Topological Phases in Mixed States
Yuchen Guo, Jian-Hao Zhang, Hao-Ran Zhang +2
We propose a tensor network approach known as the locally purified density operator (LPDO) to investigate the classification and characterization of symmetry-protected topological…
