    In bulk semiconductors, the absorption of one photon of energy greater than the bandgap leads to one exciton. In quantum dots, however, it could be possible to create multiple excitons from a single high-energy photon, a finding with dramatic implications for the efficiencies of devices such as solar cells.

    Superconductivity and antiferromagnetism are in fierce competition in high-temperature superconductors. However, this competition has the unexpected benefit that the antiferromagnetism improves the capacity of the superconductor to resist magnetic fields.
