Fractality-induced photonic topological insulators
Shuming Zhang, Zhaoxin Wu, Lumen Eek +2
Fractal lattices have recently emerged as a promising setting for topological wave physics, but in most realizations the topological character is inherited from externally engineer…

High-order exceptional points in supersymmetric arrays
S. M. Zhang, X. Z. Zhang, L. Jin +1
We employ the intertwining operator technique to synthesize a supersymmetric (SUSY) array of arbitrary size . The synthesized SUSY system is equivalent to a spin- under…

Flat band in two-dimensional non-Hermitian optical lattices
S. M. Zhang, L. Jin
We propose a method to generate a real-energy flat band in a two-dimensional (2D) non-Hermitian Lieb lattice. The coincidence of the flat band eigenstate in both real and momentum…
