Research group led by Jiangfeng Du has made significant experimental progress in non-Hermitian physics using a single-spin system. They reported the experimental observations of a non-Hermitian non-Abelian topological transition and a new type of exceptional point—the Dirac exceptional point. These two works were published in Nature Nanotechnology and Physical Review Letters with the titles "Non-Hermitian ...
