Exact mobility edges in quasiperiodic network models with slowly varying potentials
Hai-Tao Hu, Yang Chen, Xiaoshui Lin +3
Quasiperiodic models are important physical platforms to explore Anderson transitions in low dimensional systems, yet the exact mobility edges (MEs) are generally hard to be determ…
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,…
Uncovering the origin of bound state in the continuum
Zeyu Rao, Changling Zou, Yang Chen +2
Bound state in the continuum (BIC) and quasi-BIC represent a remarkable class of wave functions that disobey conventional intuition by exhibiting spatially localized modes embedded…
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…
