Direct generation of tunable orbital angular momentum beams in microring lasers with broadband exceptional points
William E. Hayenga, Jinhan Ren, Midya Parto +7
Non-Hermitian exceptional points (EPs) represent a special type of degeneracy where not only the eigenvalues coalesce, but also the eigenstates tend to collapse on each other. Rece…

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…
