Experimental Realization of Non-Abelian Permutations in a Three-State Non-Hermitian System
Weiyuan Tang, Kun Ding, Guancong Ma
Eigenstates of a non-Hermitian system exist on complex Riemannian manifolds, with multiple sheets connecting at branch cuts and exceptional points (EPs). These eigenstates can evol…

Direct Measurement of Topological Properties of an Exceptional Parabola
Weiyuan Tang, Kun Ding, Guancong Ma
Non-Hermitian systems can produce branch singularities known as exceptional points (EPs). Different from singularities in Hermitian systems, the topological properties of an EP can…
