  • Spin ices have magnetic moments arranged on a lattice with many possible ground-state configurations. Quantum effects can ‘melt’ the spin ice into a liquid that fails to form static order even at absolute zero despite strong interactions.

  • Photonic waveguides with appropriately engineered interactions allow the experimental realization of non-Abelian quantum holonomies of the symmetry group U(3), which is known from the strong nuclear force.

  • The Luttinger liquid is a theoretical concept used to describe interacting fermions in a 1D system. Now it is shown that the model also describes electron physics in η-Mo4O11, a quasi-2D material in which 1D chains cross each other.

  • Manipulating the chirality of electron vortices using attosecond metrology allows the clocking of continuum–continuum transitions, bringing the dream of time-resolved quantum physics a little closer.

  • Attosecond circular-dichroism chronoscopy—a spectroscopy technique that employs two circularly polarized pulses in co-rotating and counter-rotating geometries—can measure the amplitudes and phases of continuum–continuum transitions in electron vortices.

  • Organs in the human body have complex networks of fluid-filled tubes and loops with different geometries and topologies. By studying self-organized, synthetic tissues, the link between topological transitions and the emergence of tissue architecture was revealed.

    Research Briefing
  • During development, tissues with complex topology emerge from collections of cells with simple geometry. This process in neuroepithelial organoids is governed by two topologically distinct modes of epithelial fusion.

  • In a burning plasma, fusion-born α particles are the dominant source of heating. In such conditions, the deuterium and tritium ion energy distribution deviates from the expected thermal Maxwellian distribution.

  • Superconductivity with an anisotropy is revealed in a layered material. This result points towards a version of superconductivity where spin–orbit interactions produce a material that is resilient to external magnetic fields.

  • Inertial confinement fusion experiments reveal a departure from the expected hydrodynamic behaviour of a plasma when the fusion reactions become the primary source of plasma heating.
