Generating function for Hermitian and non-Hermitian models
Hua-Yu Bai, Yang Chen, Guang-Can Guo +2
It is well known that Hermitian and non-Hermitian models exhibit distinct physics and require different theoretical tools. In this work, we propose a unified generating-function fr…

Skin mode tunability and self-healing effect in photonic Floquet lattices
Hua-Yu Bai, Yang Chen, Tian-Yang Zhang +3
Non-Hermitian systems host exotic phenomena absent in their Hermitian counterparts, including the recently predicted self-healing effect (SHE) of non-Hermitian skin modes. To date,…

Reentrant phase transition in quasiperiodic photonic waveguides
Yang Chen, Ze-Zheng Li, Hua-Yu Bai +10
Anderson transition in quasiperiodic potentials and the associated mobility edges have been a central focus in quantum simulation across multidisciplinary physical platforms. While…
