Applying circularly polarized light to a monolayer of graphene dramatically changes how surface electromagnetic waves (or plasmons) disperse along the carbon sheet. This new result, from researchers in Sweden and The Netherlands, could not only be important for studying how charge carriers move in graphene, but could also help build graphene-based elements for the rapidly developing field of “metamaterials”……
