Super- and subradiant dynamics of quantum emitters mediated by atomic matter waves
Nature Physics, Published online: 18 November 2024; doi:10.1038/s41567-024-02676-w
Experiments on cooperative radiative decay typically involve rapidly escaping photons. Collective emission dynamics have now been studied in an array of quantum emitters interacting via atomic matter waves in a novel regime of slow propagation.

Nematic fluctuations shape Cooper pairs
Nature Physics, Published online: 13 November 2024; doi:10.1038/s41567-024-02693-9
Experimental evidence of nematic-fluctuation-mediated superconductivity has been observed in an iron-based superconductor near the quantum critical point.

Highly anisotropic superconducting gap near the nematic quantum critical point of FeSe<sub>1−<i>x</i></sub>S<sub><i>x</i></sub>
Nature Physics, Published online: 13 November 2024; doi:10.1038/s41567-024-02683-x
Superconductivity that is mediated by fluctuations of a nematic electronic order has not been experimentally demonstrated. Now an analysis of the symmetry of the superconducting gap in doped FeSe provides evidence of this phenomenon.

Islands identified
Nature Physics, Published online: 13 November 2024; doi:10.1038/s41567-024-02670-2
Filamentary eruptions from the plasma edge in fusion devices pose a critical threat to their integrity. The identification of magnetic islands at the top of the edge explains how these eruptions are suppressed by resonant magnetic perturbations.

A different facet to materials design
Nature Physics, Published online: 12 November 2024; doi:10.1038/s41567-024-02709-4
Complex oxides have competing phases with different spin, electronic and orbital order. Now it has been shown that growing thin films on different facets of a low-symmetry substrate can be used to control the phase of the ground state.

Artificial boundaries
Nature Physics, Published online: 11 November 2024; doi:10.1038/s41567-024-02717-4
The 2024 Nobel prize for Physics was awarded for foundational contributions to the development of artificial neural networks. The award reflects a shift in how we understand boundaries between scientific fields — or whether such boundaries are still useful at all.
