We explore anomalous skin effects at non-Hermitian impurities by studying their interplay with potential disorder and exactly solving a minimal lattice model. A striking feature of the solvable single-impurity model is that presence anisotropic hopping terms can induce scale-free accumulation all eigenstates opposite to bulk direction, although nonmonotonic behavior fine tuned further increasing such weakens eventually reverses effect. The disorder, however, qualitatively enriches this...
The remarkable sensitivity of non-Hermitian systems has been extensively studied and stimulated ideas about developing new types sensors. In this paper, we examine a chain parametrically driven coupled resonators governed by the squeezed Su-Schrieffer-Heeger model. We emphasize qualitative difference in sensor performance between configurations depending on bulk topology boundary modes, specifically for detecting both on-site skin effect perturbations. Our analysis goes beyond scenario...
