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…

Uniform response theory of non-Hermitian systems: Non-Hermitian physics beyond the exceptional point
Subhajyoti Bid, Henning Schomerus
Non-Hermitian systems display remarkable response effects that reflect a variety of distinct spectral scenarios, such as exceptional points where the eigensystem becomes defective.…

Geometric contribution to adiabatic amplification in non-Hermitian systems
Tomoki Ozawa, Henning Schomerus
Concepts from non-Hermitian quantum mechanics have proven useful in understanding and manipulating a variety of classical systems, such as those encountered in optics, classical me…
