Theoretical analysis of glide-Z_2 magnetic topological photonic crystals
Heejae Kim, Hengbin Cheng, Ling Lu +1
Gapped systems with glide symmetry can be characterized by a Z_2 topological invariant. We study the magnetic photonic crystal with a gap between the second and third lowest bands,…

Surface density-of-states on semi-infinite topological photonic and acoustic crystals
Yi-Xin Sha, Bo-Yuan Liu, Hao-Zhe Gao +5
Iterative Green's function, based on cyclic reduction of block tridiagonal matrices, has been the ideal algorithm, through tight-binding models, to compute the surface density-of-s…
