The non-Hermitian skin effect, or localization of eigenstates at the boundary of a non-Hermitian system, has been intensively studied. Chu et al. observe a large and wide edge supercurrent in the Dirac semimetal Cd3As2-based Josephson junctions, which is consistent with the non-Hermitian skin effect.
