    Combining the strong nonlinearity of single-photon emitters with the light-focusing characteristics of metal nanowires could soon enable the realization of a single-photon transistor — a device that would revolutionize the field of quantum optics.

    In the fractional quantum Hall effect, the quasiparticles carry fractional charge. But neutral excitations with fractional spin have been elusive in two-dimensional magnets. Is it possible that they have already been observed?

    Our social behaviour has evolved primarily through contact with a limited number of other individuals. Yet as a species we exhibit uniformities on a global scale. This kind of emergent behaviour is familiar territory for statistical physicists.

    A quantum dot is usually charged by inserting electrons. But electrons can also be removed from a neutral dot. Unexpectedly, positively charged dots are different from highly charged negative ones, which have their own peculiarities.
