Scientists observe quantum superconductor-metal transition and superconducting glass

A new article presents the results of the first experimental study of the graphene-based quantum phase transition of the “superconductor-to-metal” type, i.e. transformation of the system’s ground state from superconducting to metallic, upon changing the electron concentration in graphene sheet.
