  • It has been suggested that Gaussian boson sampling may provide a quantum computational advantage for calculating the vibronic spectra of molecules. Now, an equally efficient classical algorithm has been identified.

  • Predicting the complex flows that emerge in active fluid networks remains a challenge. A combination of experiments and theory was used to determine the hydraulic laws of active fluids. Analogies with frustrated magnetism and loop models explain the emergent flow patterns that result when active fluids explore pipe networks.

  • Cells actively rearrange their cytoplasmic machinery to perform diverse functions. Now, friction forces generated between cytoplasmic components provide a physical basis for cell shape change.

  • A promising pathway towards the laser cooling of a molecule containing a radioactive atom has been identified. The unique structure of such a molecule means that it can act as a magnifying lens to probe fundamental physics.

  • Experiments with active colloidal fluids in large-scale hydraulic networks reveal a connection between emergent flows and dynamical spin-ice patterns.

  • Orderly or coherent multicellular flows are fundamental in biology, but their triggers are not understood. In epithelial tissues, the tug-of-war between cells is now shown to lead to intrinsic asymmetric distributions in cell polarities that drive such flows.

  • An error detecting code running on a trapped-ion quantum computer protects expressive circuits of eight logical qubits with a high-fidelity and partially fault-tolerant implementation of a universal gate set.

  • The Haldane model is a paradigmatic example of topological behaviour but has not previously been implemented in condensed-matter experiments. Now a moiré bilayer is shown to realize this model with the accompanying quantized transport response.

  • The ability to extract information from diffuse background signals in ultrafast electron diffraction experiments now enables a direct view of the formation of topological defects during a light-induced phase transition.

  • Subwavelength photonic gratings can host long-lived, negative-effective-mass photonic modes that couple strongly to electron transitions in constituent active materials. The resulting bosonic hybrid light–matter modes, or exciton-polaritons, can be optically configured to accumulate into various macroscopic artificial complexes and lattices of coherent quantum fluids.

    Research Briefing
  • Networks of dynamic actin filaments and myosin motors, confined in cell-like droplets, drive diverse spatiotemporal patterning of contractile flows, waves, and spirals. This multiscale active sculpting is tuned by the system dynamics and size.
