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…

Competing pair density wave orders in the square lattice - model
Wayne Zheng, Zheng-Yuan Yue, Jian-Hao Zhang +1
Over the last two decades, the competing orders in high- cuprates have been intensely studied, such as pseudogap phase, charge density waves (CDW), and pair density waves (P…

Correspondence of boundary theories between internal and crystalline symmetry protected topological phases
Jian-Hao Zhang, Shang-Qiang Ning
Symmetry-protected topological phases protected by crystalline symmetries and internal symmetries are shown to enjoy a fascinating one-to-one correspondence in classification. Here…
