Experimental Demonstration of Controllable and Anti- Coupling in a Non-Hermitian Metamaterial
Non-Hermiticity has recently emerged as a rapidly develo** field due to its exotic
characteristics related to open systems, where the dissipation plays a critical role. In the …

General theory for infernal points in non-Hermitian systems
SX Wang, Z Yan - Physical Review B, 2024 - APS
The coalescence of eigenstates is a unique phenomenon in non-Hermitian systems.
Remarkably, it has been noticed in some non-Hermitian systems under open boundary …

Creating compact localized modes for robust sound transport via singular flat band engineering
R Emanuele, F Bellinzoni, F Braghin - arxiv preprint arxiv:2411.05610, 2024 - arxiv.org
We experimentally demonstrate the emergence of flat-band-induced compact-localized
modes in acoustic Kagome lattices. Compact localized states populate singular dispersion …
