Researchers at the University of Hong Kong demonstrate negative light refraction with the natural magnetic material CrSBr – ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...
