The Graphene Supersolid Breakthrough Explained
The Graphene Supersolid Breakthrough A supersolid is one of condensed-matter physics’ most counterintuitive ideas: a material that develops crystal-like spatial order while still retaining a phase-coherent, frictionless “superfluid” character. Recent work in double-layer graphene reports transport behavior consistent with an exciton superfluid that can transition into a low-temperature insulating phase suggestive of an ordered exciton solid—followed by a surprising recovery [...]
