Exact solution of non-Hermitian systems with generalized boundary conditions: size-dependent boundary effect and fragility of the skin effect
CX Guo, CH Liu, XM Zhao, Y Liu, S Chen - Physical Review Letters, 2021 - APS
Systems with non-Hermitian skin effects are very sensitive to the imposed boundary
conditions and lattice size, and thus an important question is whether non-Hermitian skin …
