Tidal surface states as fingerprints of non-Hermitian nodal knot metals

[摘要] Non-Hermitian systems have opened up a new level of complexity to non-trivial topological phases, particularly on the bulk-boundary correspondence in higher dimensions. Here, the authors developed a theoretical framework of tidal surface states for gapless nodal non-Hermitian metals, and explain their realizations with topolectrical circuits.
