Superfluid Freezes into Supersolid, Defying Physics Expectations
Physicists have observed a superfluid, typically characterized by its frictionless flow, transition into a supersolid state, a phenomenon previously thought impossible. This discovery was made using ultra-thin graphene, where researchers from Columbia University and the University of Texas at Austin noted that the superfluid stopped moving, forming a solid-like structure while retaining quantum properties. This phase transition, akin to water freezing into ice, represents a significant breakthrough in understanding quantum matter. The research, published in Nature, suggests that this supersolid state combines the ordered structure of a solid with the fluidity of a superfluid, challenging long-standing assumptions in condensed matter physics.
