Exceptional activated mode theory for generalized real-complex transitions
Mengjie Yang, Alexander N. Poddubny, Ching Hua Lee
Real-to-complex spectral transitions mark the onset of amplification in non-Hermitian systems, but their thresholds are often treated as model-specific quantities. Here we develop…
Nonlocality-induced critical-length hierarchy from non-Hermitian competition
Mengjie Yang, Alexander N. Poddubny, Ching Hua Lee
Spectral transitions in non-Hermitian lattices often arise from the competition between non-reciprocal skin accumulation and inter-component hybridization. In short-range systems f…
Occupation-selective topological pumping from Floquet gauge fields
Wenjie Liu, Ching Hua Lee, Zhoutao Lei
Topological pumping is conventionally governed by single-particle band topology. Here we show that promoting tunneling to a dynamical, occupation-conditioned variable fundamentally…
