"Our team experimentally detected an exceptional surface, a continuous three-dimensional curving surface of exceptional points," said Xufeng Zhang, who led this international research project and works as an assistant scientist at the Center for Nanoscale Materials (CNM) at Argonne, a DOE Office of
"Our original contribution is to have mapped three-dimensional surfaces of exceptional points based on experimental measurements, and the result is strikingly beautiful graphs."Xufeng Zhang, assistant scientist at the Center for Nanoscale Materials
