Second-order topological non-Hermitian skin effects

R Okugawa, R Takahashi, K Yokomizo - Physical Review B, 2020 - APS
Higher-order topology realizes topologically robust corner modes as a manifestation of
nontriviality. We theoretically propose non-Hermitian skin effects which stem from the second-…
