Topological Edge and Corner States in Biphenylene Photonic Crystal
Huyen Thanh Phan, Keiki Koizumi, Feng Liu +1
The biphenylene network (BPN) has a unique two-dimensional atomic structure, where hexagonal unit cells are arranged on a square lattice. Inspired by such a BPN structure, we desig…

Valley-dependent Corner States in Honeycomb Photonic Crystal without Inversion Symmetry
Huyen Thanh Phan, Feng Liu, Katsunori Wakabayashi
We study topological states of honeycomb photonic crystals in absence of inversion symmetry using plane wave expansion and finite element methods. The breaking of inversion symmetr…
