<p>➀ Scientists from Johns Hopkins University, the University of British Columbia, and the University of Washington discovered a new class of quantum states in a specially designed graphene structure: topological electronic crystals in twisted bilayer-trilayer graphene.</p><p>➁ Ruiheng Su, an undergraduate student at UBC, discovered a new configuration for the device while working on the experiment at Folk's lab. The electrons in the graphene froze into a perfectly ordered array, flowing smoothly along the sample's borders while remaining immobile inside.</p><p>➂ The research reveals that the topological electronic crystal can conduct electricity along its boundaries despite forming an ordered array, opening up new avenues for breakthroughs in quantum information.</p>
