Symmetry constraints on topological invariants and irreducible band representations
Jing Zhang
EBR is considered the building block in TQC and fundamental concept in SI methods. One of the hypophysis is that a fully occupied EBR has zero Berry-Wilczek-Zee phase and those occ…

Band representation, band connectivity and irreducibility
Jing Zhang
The BR, formulated by Zak in the 80s, is widely used in studies of topological phase of material. EBR are considered the building block of TQC. However, there were debate on whethe…
