Boundary Floquet Control of Bulk non-Hermitian Systems
Yu-Min Hu, Yu-Bo Shi, Linhu Li +5
Boundary perturbations are generally irrelevant for bulk properties in the thermodynamic limit, as they are edge-confined and subextensive. We show that this expectation breaks dow…

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…
