Non-Hermitian skin effect and chiral dam** in open quantum systems

F Song, S Yao, Z Wang - Physical review letters, 2019 - APS
One of the unique features of non-Hermitian Hamiltonians is the non-Hermitian skin effect,
namely, that the eigenstates are exponentially localized at the boundary of the system. For …
