Optical Lattices with Higher-order Exceptional Points by Non-Hermitian Coupling
Xingping Zhou, Samit Kumar Gupta, Zhong Huang +5
Exceptional points (EPs) are degeneracies in open wave systems with coalescence of at least two energy levels and their corresponding eigenstates. In higher dimensions, more comple…
