Exceptionally deficient topological square-root insulators
Subhajyoti Bid, Henning Schomerus
One of the most surprising features of effectively non-Hermitian physical systems is their potential to exhibit a striking nonlinear response and fragility to small perturbations.…

Fragmented exceptional points and their bulk and edge realizations in lattice models
Subhajyoti Bid, Henning Schomerus
Exceptional points (EPs) are spectral defects displayed by non-Hermitian systems in which multiple degenerate eigenvalues share a single eigenvector. This distinctive feature makes…

Generalized Petermann factor of non-Hermitian systems at exceptional points
Julius Kullig, Jan Wiersig, Henning Schomerus
The nonorthogonality of modes in open systems significantly modifies their resonant response, resulting in quantitative and qualitative deviations from Breit-Wigner resonance relat…
