Extended Data Table 1 Chern insulating states in a two dimensional lattice classified by whether quantum numbers C and s are integer (\({\mathbb{Z}}\)) or noninteger rational numbers (\({\mathbb{Q}}\backslash {\mathbb{Z}}\)). C is the net Chern number and s is the number of electrons bound to each lattice unit cell
