    Nanomagnets are often used to build artificial systems that are geometrically frustrated, but when quasiperiodic ordering is introduced, an unusual ground state can form, with an ordered skeletal structure surrounding groups of degenerate macrospins.

    Exploiting the magnetic field-induced shift of entropy in certain molecular salts when going from 1D short-range ordering to a 3D quantum critical point could provide a route for producing strongly fluctuating quantum materials.

    Theory and experiment show that quantum correlations violate the instrumental test—a common statistical method used to estimate the strength of causal relationships between two variables.

    The arrival of a new type of timekeeper heralds the end of the second as we know it, as Helen Margolis explains.

    Atomically thin chromium tri-iodide is shown to be a 2D ferromagnetic insulator with an optical response dominated by ligand-field transitions, emitting circularly polarized photoluminescence with a helicity determined by the magnetization direction.

    The effect of blackbody radiation is expected to be very weak. The acceleration due to the attractive optical forces from blackbody radiation is measured in an atom interferometer and, surprisingly, it dominates gravity and radiation pressure

    Large spin–orbit coupling can be induced when graphene interfaces with semiconducting transition metal dichalcogenides, leading to strongly anisotropic spin dynamics. As a result, orientation-dependent spin relaxation is observed.

    For a system to exhibit spiral patterns one would expect its parts to behave synchronously, as in a Mexican wave. Proving the contrary, chemical oscillators have now been observed in a state comprising a spiral surrounding an asynchronous core.

    The topological valley Hall effect was predicted as a consequence of the bulk topology of electronic systems. Now it has been observed in photonic crystals, showing that both topology and valley are innate to classical as well as quantum systems.

    Droplets moving on the surface of a vibrating fluid bath mimic the behaviour of electrons in quantum corrals. Introducing submerged features in the bath can even drive the droplets to excite modes that induce effects reminiscent of quantum mirages.

    Attosecond light pulses are used to probe ultrafast processes. The experimental observation of attosecond electron pulses now promises the marriage of these techniques with electron microscopy and diffraction.

    Understanding how some single cells evolved into multicellular life means figuring out how they overcome the stresses associated with crowding as they multiply. New insights from yeast suggest that changes in the shape of cells may provide an answer.

    Classical wave-driven particles can mimic basic quantum properties, but how far this parallel extends is yet to be seen. Evidence for quantum-like mirages in a system of droplets moving on a fluid surface pushes the analogy into many-body territory.
