    Observation of a many-body pairing gap in a trapped, 2D atomic Fermi gas shows that ultracold atomic gases can be used to emulate the physics of correlated 2D superconductors, with the ultimate goal of understanding high-temperature superconductivity.

    Quantum computing architectures based on hybrid systems require strong coupling and information exchange between their constituent elements. These two features have been achieved in one such hybrid setting. See Letter p.221

    Extensive mapping of local electronic structure in copper oxide superconductors reveals fluctuating stripe-like electron patterns that appear as a high-temperature precursor to superconductivity. See Letter p.677

    The superconducting phase of a superconductor is often one of several competing types of electronic order, including antiferromagnetism and charge density waves. For some superconductors, the superconducting transition temperature can be maximized by forcing the critical temperature of the competing order down to zero. Now, a related effect has been identified in a high-temperature superconductor, with the application of pressure yielding a striking two-step increase in the transition temperature.

    The oxygen interstitials in the layers separating the superconducting CuO2 planes undergo ordering phenomena in La2CuO4+y that enhance the transition temperature (Tc). It is also known that complex systems often have a scale-invariant structural organization, but hitherto none had been found in high-Tc materials. These authors report that the ordering of oxygen interstitials in the La2O2+y spacer layers of La2CuO4+y high-Tc superconductors is characterized by a fractal distribution up to a maximum limiting size of 400 µ.

    Measurements of X-ray diffraction on small patches of a copper oxide superconductor reveal that oxygen crystal defects form fractal structures that seem to promote high-temperature superconductivity.

    In the high-transition-temperature superconductors, the pseudogap phase becomes predominant when the density of doped holes is reduced. In this phase it has been unclear which electronic symmetries (if any) are broken, what the identity of any associated order parameter might be, and which microscopic electronic degrees of freedom are active. Here, images of the intra-unit-cell states in underdoped Bi2Sr2CaCu2O8 + δ are studied, revealing electronic nematicity of the states close to the pseudogap energy.

    The discovery that the face-centred cubic form of the fullerene Cs3C60 is a superconductor, just as its body-centred cubic counterpart is, sheds light on the origin of superconductivity in organic materials.

    Superconductivity has been discovered in the materials that form when alkali metals react with a solid hydrocarbon. This is the first new class of organic, high-temperature superconductor in a decade.
