How Long-Range Tails Reshape Non-Hermitian Spectra
Ding Gu, Zhanpeng Fu, Yu-Min Hu +1
Exponentially decaying long-range hoppings are ubiquitous in realistic tight-binding models and are often truncated to obtain a finite-range description. We show that this approxim…

Nonreciprocity-enriched steady phases in open quantum systems
Ding Gu, Zhanpeng Fu, Zhong Wang
Nonreciprocity can profoundly alter the spectra and dynamics of open quantum systems, yet its impact on the long-time steady-state phases of matter has remained largely unexplored.…
