Observation of Dislocation Bound States and Skin Effects in Non‐Hermitian Chern Insulators
Advanced Materials, EarlyView.Experimental observation of the dislocation‐induced bound states and skin effects is demonstrated in a line‐gap non‐Hermitian acoustic lattice. By utilizing active meta‐atoms to measure the full complex spectrum and biorthogonal eigenstates, the study reveals the exceptional‐point‐driven melting of defect modes.
