    An atomic simulator formed of a few ultracold fermionic atoms trapped in a two-dimensional harmonic potential exhibits precursors of a quantum phase transition, revealing the onset of collective quantum many-body phenomena in a few-body system.

    Simulations using machine-learning-based interatomic potentials in dense hydrogen overcome system size and timescale limitations, providing evidence of a supercritical behaviour of high-pressure liquid hydrogen and reconciling theoretical and experimental discrepancies.

    Study of WSe2/WS2 moiré superlattices reveals the phase diagram of the triangular-lattice Hubbard model, including a Mott insulating state at half-filling and a possible magnetic quantum phase transition near 0.6 filling.

    The ferromagnet CeRh6Ge4 is found to exhibit strange-metal behaviour at a quantum critical point, suggesting that changes in the pattern of quantum entanglement, not antiferromagnetism, underlie the development of strange metals.

    A driven–dissipative gas of ultracold potassium atoms is used to demonstrate three key signatures of self-organized criticality, and provides a system in which the phenomenon can be experimentally tested.

    A model demonstrates that people who eventually succeed and those who do not may initially appear similar, but are characterized by fundamentally distinct failure dynamics in terms of the efficiency and quality of each subsequent attempt to succeed.

    X-ray diffraction measurements of solid hydrogen provide crystallographic information for high-pressure phases of hydrogen and transitions between them, suggesting a series of isostructural transitions under compression before band closure and metallization.

    Quantum critical behaviour at the many-body localization transition in a disordered Bose–Hubbard system of bosonic rubidium atoms in an optical lattice is observed, connecting the macroscopic phenomenology of the transition to the system’s microscopic quantum correlations.

    Colossal barocaloric effects are observed in the plastic crystal neopentylglycol and found to originate from the extensive molecular orientational disorder, giant compressibility and highly anharmonic lattice dynamics of the material.

    A fundamentally different approach to designing solid oxide electrolytes is presented, using a phase transition to suppress electronic conduction in a correlated perovskite nickelate; this yields ionic conductivity comparable to the best-performing solid electrolytes in the same temperature range.
