    The splitting of zero-energy Majorana modes in a tunnel-coupled InAs nanowire with epitaxial aluminium is exponentially suppressed as the wire length is increased, resulting in protection of these modes; this result helps to establish the robust presence of Majorana modes and quantifies exponential protection in nanowire devices.

    To be able to control the properties of a system that has strong electron–electron interactions using only an external electric field would be ideal, but the material must be thin enough to avoid shielding of the electric field in the bulk material; here pure electric-field control of the charge-density wave and superconductivity transition temperatures is achieved by electrolyte gating through an electric-field double layer transistor in the two-dimensional material 1T-TiSe2.

    By harnessing the charge transfer that takes place at the interface between a metal and a layer of molecules, the usually non-magnetic materials copper and manganese are made magnetic at room temperature.

    Measurements and simulations of several high-mobility conjugated polymers show that their charge transport properties reflect an almost complete lack of disorder in the polymers, despite their amorphous microstructures, resulting from the resilience of the planar polymer backbone conformations to side-chain disorder.

    The insertion of an insulating layer into a multilayer light-emitting diode (LED) based on quantum dots and produced by depositing the layers from solution increases the performance of the LEDs to levels comparable to those of state-of-the-art organic LEDs produced by vacuum deposition, while retaining the advantages of solution processing.

    Nanoribbons of graphene grown on electronics-grade silicon carbide conduct electrons much better than expected; at room temperature, the charge carriers travel through the nanoribbons without scattering for a surprisingly long distance, more than ten micrometres.

    An experimental demonstration of the concept of a ‘quantum access network’ based on simple and cost-effective telecommunication technologies yields a viable method for realizing multi-user quantum key distribution networks with efficient use of resources.

    A continuous-wave Raman silicon laser with a photonic-crystal nanocavity less than ten micrometres in size and an unprecedentedly low lasing threshold of one microwatt is demonstrated, showing that the integration of all-silicon devices into photonic circuits may be possible.

    The drive to improve digital memory through ever-shrinking electronic circuitry will ultimately face a bottleneck. Researchers propose exploiting the room 'inside' memory elements as a solution.

    A new family of resonators for nanoscale lasers is described that allows the size of the laser cavity to be scaled down without increasing the threshold power required to drive lasing.
