Emergence, Coalescence, and Topological Properties of Multiple Exceptional Points and Their Experimental Realization
Non-Hermitian systems distinguish themselves from Hermitian systems by exhibiting a phase transition point called an exceptional point (EP), at which two eigenstates coalesce under a system parameter variation. Many interesting EP phenomena, such as level crossings in nuclear and condensed matter ph...
