Non-Hermitian corner skin effect in a two-dimensional photonic crystal
Huyen Thanh Phan, Katsunori Wakabayashi
We numerically study topological effects of electromagnetic (EM) waves in a two-dimensional (2D) non-Hermitian photonic crystal (PhC) composed of lossy magneto-optical materials. I…
Wilson Loop and Topological Properties in 3D Woodpile Photonic Crystal
Huyen Thanh Phan, Shun Takahashi, Satoshi Iwamoto +1
We numerically study the first and the second order topological states of electromagnetic (EM) wave in the three-dimensional (3D) woodpile photonic crystal (PhC). The recent studie…
Topological Edge and Corner States in Biphenylene Network
Keiki Koizumi, Huyen Thanh Phan, Kento Nishigomi +1
The electronic states and topological properties of the biphenylene network (BPN) are analyzed using a tight-binding model based on the -electron network. It is shown that tunin…
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…
Microwave hinge states in a simple-cubic-lattice photonic crystal insulator
Shun Takahashi, Yuya Ashida, Huyen Thanh Phan +4
We numerically and experimentally demonstrated a higher-order topological state in a three-dimensional (3D) photonic crystal (PhC) with a complete photonic bandgap. Two types of cu…
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…
