Sensing with exceptional surfaces: combining sensitivity with robustness
Q. Zhong, J. Ren, M. Khajavikhan +3
Exceptional points (EPs) are singularities that arise in non-Hermitian physics. Current research efforts focus only on systems supporting isolated EPs characterized by increased se…

Winding around Non-Hermitian Singularities: General Theory and Topological Features
Qi Zhong, Mercedeh Khajavikhan, Demetrios Christodoulides +1
Non-Hermitian singularities are ubiquitous in non-conservative open systems. These singularities are often points of measure zero in the eigenspectrum of the system which make them…
