Scientists develop ‘exceptional’ surface to explore exotic physics

(ORDO NEWS) — By demonstrating exceptional control of an open optical system, an international research team has provided a path to experimentally measure and test exotic phenomena and gain insights into new physics with exquisite sensitivity. Reported in Nature Communications, the Penn State, Michigan Technological University and Vienna University of Technology researchers created a stable surface of “exceptional” points—notoriously finicky singularities that exhibit peculiar properties—and used it to facilitate and observe the perfect absorption of light in a coherent, chiral…
