Physicists create optical phenomenon inspired by the quantum Hall and spin Hall effects

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum Hall and spin Hall effects to a hybrid light-matter system by harnessing targeted material design. The team led by Professor Sebastian Klembt generated this optical quantum phenomenon by using polaritons-hybrid light-matter particles. This advance paves the way for optical information processing. The results have been published in Nature Communications.
