• Controlling electrons in graphene opens a new path to potential electronic devices

    9 days ago - By Phys.org

    For the first time, scientists created a tunable artificial atom in graphene. They demonstrated that a vacancy in graphene can be charged in a controllable way such that electrons can be localized to mimic the electron orbitals of an artificial atom. Importantly, the trapping mechanism is reversible and the energy levels can be tuned.

  • Physicists demonstrate new way to violate local causality

    9 days ago - By Phys.org

    For the first time, physicists have experimentally demonstrated the violation of "bilocal causality"-a concept that is related to the more standard local causality, except that it accounts for the precise way in which physical systems are initially generated. The results show that it's possible to violate local causality in an entirely new and more general way, which could lead to a potential new resource for quantum technologies.
