Beyond the non-Hermitian skin effect: scaling-controlled topology from Exceptional-Bound Bands
Mengjie Yang, Ching Hua Lee
We establish a novel mechanism for topological transitions in non-Hermitian systems that are controlled by the system size. Based on a new paradigm known as exceptional-bound (EB)…

Reversing non-Hermitian skin accumulation with a non-local transverse switch
Mengjie Yang, Ching Hua Lee
Asymmetrically directed couplings in non-Hermitian systems cause directional amplification that leads to boundary skin state accumulation. However, counter-intuitively, the directi…

Beyond symmetry protection: Robust feedback-enforced edge states in non-Hermitian stacked quantum spin Hall systems
Mengjie Yang, Ching Hua Lee
Conventional wisdom holds that, in the simplest time-reversal-symmetric setting, strongly coupling two QSH layers yields a trivial phase and no protected topological…
