Researchers have witnessed a superfluid in graphene halt its motion, transitioning into a supersolid—a quantum phase blending solid-like order with frictionless flow. This breakthrough, achieved in bilayer graphene under specific conditions, challenges long-held assumptions about quantum matter. The findings, published in Nature, mark the first natural observation of such a phase without artificial constraints.
