Analysis of the anisotropy of the magnetic excitations in the nematic state of an iron-based superconductor suggests that this phase is driven primarily by spin fluctuations.

Quantum waves can have stronger correlations than classical ones because of their particle nature. This effect has now been observed using quantum sound waves travelling in an acoustic waveguide.

The mechanism that drives nematic behaviour in iron-based superconductors is still unclear. Now, nematicity and anisotropy in spin excitations are shown to disappear at the same temperature, indicating that the transition is primarily spin-driven.

The appearance of small local gaps in the electronic band structure of a topological semimetal is attributed to a hidden quasi-symmetry that produces a large Berry curvature.

The concept of quasi-symmetry—a perturbatively small deviation from exact symmetry—is introduced and leads to topological materials with strong resilience to perturbations.

Electrical readout of the state of an antiferromagnet is an important goal for spintronic applications. Now, detection of the electrical voltage created by a thermal gradient in a canted antiferromagnet suggests a route for achieving this goal.
