Abstract
The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with nonzero bulk invariants predicting its appearance and its position in real space. Here we demonstrate that the non-Hermitian skin effect has weaker bulk-edge correspondence than topological insulators: when translation symmetry is broken by a single non-Hermitian impurity, skin modes are depleted at the boundary and accumulate at the impurity site, without changing any bulk invariant. Similarly, a single non-Hermitian impurity may deplete the states from a region of Hermitian bulk.
Author indications on fulfilling journal expectations

- Present a breakthrough on a previously-identified and long-standing research stumbling block
Author comments upon resubmission
Dear editor,
We have now responded to the referees and attached a redlined version of the manuscript with marked changes compared to the previous submission to our responses.
We believe that we have addressed the main concerns expressed in report 5 by clarifying the manuscript and addressing some of the misunderstanding.
Best regards,
The authors
