What's Happening?
Researchers at the University of Göttingen, in collaboration with teams from Braunschweig, Bremen, and Fribourg, have made a significant breakthrough in quantum materials by observing Floquet effects in graphene.
Graphene, known for its stability and high conductivity, is a single atom-thin layer of carbon atoms. The study, published in Nature Physics, demonstrates that Floquet engineering, which uses precise light pulses to adjust material properties, can be applied to metallic and semi-metallic quantum materials like graphene. This discovery was achieved using femtosecond momentum microscopy, a method that involves stimulating the material with fast light bursts and inspecting it with a second pulse. The findings confirm that Floquet effects occur in the photoemission spectrum of graphene, opening new possibilities for controlling electronic states in quantum materials.
