    The authors fabricate a fluxonium circuit using a granular aluminium nanoconstriction to replace the conventional superconductor–insulator–superconductor tunnel junction. Their characterization suggests that this approach will be a useful element in the superconducting qubit toolkit.

    Both bosonic and fermionic collective states can emerge in two-dimensional semiconductor lattices, and mixing these species can further expand the landscape of quantum phases. Here, the authors report Bose–Fermi mixtures of neutral and charged excitons and the emergence of dual-density waves in an electrostatic lattice in a GaAs bilayer.

    The authors report a crossover from easy-plane to easy-axis magnetic anisotropy in monolayer RuCl3, which they attribute to an in-plane distortion of the Cl atoms observed in electron diffraction that modify the non-Kitaev exchange terms. The results are useful for overcoming the challenge of realizing a quantum spin liquid.

    Two-dimensional electrons on the surface of an electride are found to exhibit a phase transition from a normal Fermi liquid to an interesting quantum liquid, which is probably a quantum version of an electronic crystal beyond the melting point.

    Engineering inter-triplet exchange coupling allows spin mixing between singlet and quintet manifolds in triplet–triplet pair states in metal–organic frameworks, demonstrating increased room-temperature triplet-fusion rates under relatively small applied magnetic fields.

    The manuscript reports on the experimental observation of a Lifshitz transition in a topological insulator HfTe5 subject to a strong magnetic field, which results in the formation of topological one-dimensional Weyl modes in the bulk of a three-dimensional material.

    Quantum materials show emergent electronic properties and related functions that are profoundly described by quantum mechanics beyond the semi-classical picture of electrons. Here, key developments and progress in the last two decades are surveyed and future challenges outlined.

    The authors present evidence for the formation of commensurate charge order in non-superconducting thin films of infinite-layer nickelates, whereas they find no charge order in a superconducting film.

    Understanding the ion intercalation and degradation mechanisms occurring during realistic battery operation is crucial to developing high-rate battery electrodes. Operando optical scattering microscopy is now used to study single-particle kinetic state-of-charge heterogeneities and cracking in high-rate Li-ion anode materials.

    Unlike electron spins, nuclear spins in van der Waals materials remain a largely untapped quantum resource. Here we report the fast coherent control of nuclear spins and strong electron-mediated nuclear–nuclear spin coupling in hexagonal boron nitride.

    Solid-state ionic conduction is a key enabler of electrochemical energy storage and conversion. A quantitative framework for ionic conduction between atomistic and macroscopic timescales in β- and β″-aluminas is now proposed for ‘atoms-to-device’ multiscale modelling and optimization.

    Knowledge of band structure aids in understanding charge transport behaviour, yet it has proved impossible to measure the conduction (LUMO) band of organic semiconductors, in particular due to sample degradation by the electron beam. To address this, the authors developed and used AR-LEIPS to reveal the LUMO band dispersion of pentacene.

    Colour centre emission from hexagonal boron nitride (hBN) holds promise for quantum technologies but activation and tuning are challenging. Here, the authors show twist-angle emission brightness tuning and external voltage brightness modulation at the twisted interface of hBN flakes.

    Superconductivity is reported in magic-angle twisted four-layer and five-layer graphene systems. While they find that all magic-angle graphene systems fit into a unified hierarchy of systems that share a set of flat bands in their electronic band structures, they also report that there is a key distinction between magic-angle twisted bilayer graphene and the other family members, related to the difference in the way the electrons move between the layers in a magnetic field.

    Spins become polarized along their momenta when travelling through chiral tellurium nanowires. The signs of chirality and current determine the orientations of polarized spins while the spin density can be tuned by electrical gating, current and external magnetic field.

    Slit-like nanochannels of pristine graphite and activated carbon, fabricated by van der Waals assembly of pristine or sculpted graphite crystals, enable comprehensive ionic response measurements and the systematic realization of their ion transport properties. These are attributed to optimal combinations of (mobile) surface charge and slippage effects at the channel wall surface in both pristine and activated nanochannels.

    Cu2O is a promising platform to host Rydberg exciton–polaritons, where excitons strongly couple to cavity photons, however their realization has been elusive. Here, the authors report Rydberg exciton–polaritons with principal quantum numbers up to n = 6.

    Superionic lithium conductivity has only been observed in a few classes of materials, mostly in thiophosphates but rarely in oxides. Corner-sharing connectivity in an oxide crystal structure framework is now shown to promote superionic conductivity.

    Integer topological defects promote cellular self-organization, leading to the formation of complex cellular assemblies that trigger cell differentiation and the formation of swirling cellular pillars once differentiation is inhibited. These findings suggest that integer topological defects are important modulators of cellular differentiation and tissue morphogenesis.
