A Chern insulator is a building block of many topological quantum matters. Here, we discuss a nonsymmorphic Chern insulator, which preserves the nonsymmorphic symmetry and breaks the time-reversal symmetry. It consists of two half-filled Chern insulators, and the bulk energy spectrum is obtained fro...
