The ground state of charge-neutral bilayer graphene in a strong magnetic field is not fully determined. Now thermal transport measurements show an absence of heat flow through that state, suggesting that its collective excitations could be gapped.

- Absence of heat flow in <i>ν</i> = 0 quantum Hall ferromagnet in bilayer graphene
- Fast quantum gas formation via electromagnetically induced transparency coolingNature Physics, Published online: 28 October 2024; doi:10.1038/s41567-024-02677-9 Current methods for directly cooling atomic gases to quantum degeneracy involve time-consuming steps. A method based on electromagnetically induced transparency now achieves quantum degeneracy with a notable reduction in preparation time.
- Observation of magnetic islands in tokamak plasmas during the suppression of edge-localized modesNature Physics, Published online: 28 October 2024; doi:10.1038/s41567-024-02666-y The suppression of edge-localized modes in tokamak plasmas is crucial to prevent them from damaging the walls of the chamber. Now experiments confirm the role that magnetic islands play in suppressing these detrimental modes.
- The cost of cellular patternsNature Physics, Published online: 28 October 2024; doi:10.1038/s41567-024-02687-7 The cell cortex consists of a chemical and a mechanical subsystem, but how energy is allocated between them is unknown. Now, measurements of the entropy production rate have revealed what determines the cell cortex’s energy budget.
- Quantum tunnelling with tunable spin geometric phases in van der Waals antiferromagnetsNature Physics, Published online: 22 October 2024; doi:10.1038/s41567-024-02675-x It is difficult to control the geometric phase of particles as they undergo quantum tunnelling. Now tuning of the geometric phase of electron spin is demonstrated in tunnelling in a multilayer van der Waals antiferromagnet.
- In-beam spectroscopy reveals competing nuclear shapes in the rare isotope <sup>62</sup>CrNature Physics, Published online: 18 October 2024; doi:10.1038/s41567-024-02680-0 Islands of inversions are regions of the nuclear chart where deformed configurations are energetically favoured over spherical ones. Now experiments show that 62Cr assumes different shapes with excitation energy, which is a signature of such islands.
