Boundary Floquet driving reconstructs bulk spectra and dynamics in non-Hermitian skin-effect systems via a new Floquet non-Bloch band theory valid at arbitrary frequencies.
A new interaction-mediated drag-induced non-Hermitian skin effect is proposed for Bose-Fermi mixtures with asymmetric bosonic tunneling.
Feedback-directed circuits on IBM quantum processors produce robust asymmetry in random dynamics distinct from the non-Hermitian skin effect.
