First-principle calculation of Chern number in gyrotropic photonic crystals

24 Jan 2020 Zhao Ran Xie Guo-Da Chen Menglin L. N. Lan Zhihao Huang Zhixiang Sha Wei E. I.

As an important figure of merit for characterizing the quantized collective behaviors of the wavefunction, Chern number is the topological invariant of quantum Hall insulators. Chern number also identifies the topological properties of the photonic topological insulators (PTIs), thus it is of crucial importance in PTI design... (read more)
