Steering of topological criticality in the Su-Schrieffer-Heeger chain via non-Hermitian substitutional impurities

We investigate the topological phase in a one-dimensional Su-Schrieffer-Heeger (SSH) chain in the presence of a finite concentration of non-Hermitian substitutional impurities. Our primary focus is the discovery of a deterministic mechanism to actively reconfigure the topological phase boundaries by introducing site-de...
