Nature Physics offers news and reviews alongside top-quality research papers in a monthly publication, covering the entire spectrum of physics. Physics addresses the properties and interactions of matter and energy, and plays a key role in the development of a broad range of technologies. To reflect this, Nature Physics covers all areas of pure and applied physics research. The journal focuses on core physics disciplines, but is also open to a broad range of topics whose central theme falls within the bounds of physics.

- Continuous recoil-driven lasing and cavity frequency pinning with laser-cooled atomsNature Physics, Published online: 11 April 2025; doi:10.1038/s41567-025-02854-4 Experiments with cold atoms in optical cavities are often limited to discontinuous operation due to reloading requirements. Now, continuous lasing is demonstrated with strontium atoms in a ring cavity, stabilized by atom loss mechanisms.
- Topological dynamics of rapid non-planar gaits in slithering snakesNature Physics, Published online: 10 April 2025; doi:10.1038/s41567-025-02835-7 Snakes are capable of non-planar gaits, such as sidewinding. Now observations of juvenile anacondas reveal another non-planar gait resembling an S shape. Calculations show how topological dynamics of active filaments enable such movements.
- Mode-resolved, non-local electron–phonon coupling in two-dimensional spectroscopyNature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02861-5 Probing electron–phonon matrix elements in bulk materials is difficult. Now, an all-optical experimental approach is demonstrated that extracts phonon-mode- and electron-energy-resolved electron–phonon matrix elements in the bulk.
- Concurrent spin squeezing and field tracking with machine learningNature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02855-3 Simultaneous spin squeezing and the detection of dynamic fields is challenging as entanglement generation and signal interrogation often interfere. An experiment now demonstrates stable spin squeezing and field tracking in a hot atomic ensemble.
- Bacterial second messengers achieve extraordinary signal capacityNature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02856-2 Second messengers are intracellular signalling molecules that relay environmental changes and prompt cellular responses. Through an information-theory framework coupled with quantitative experiments, the second-messenger molecule cAMP, in the bacterium Pseudomonas aeruginosa, is shown to achieve information transmission rates of up to 40 bits per hour.
- Resourceful dissipationNature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02881-1 Controlled dissipation enables the extraction of equilibrium properties of ultracold one-dimensional gases through the observation of anomalous dynamics.
- The strongly driven Fermi polaronNature Physics, Published online: 07 April 2025; doi:10.1038/s41567-025-02799-8 Fermi polarons are quasiparticles formed by impurities immersed in a Fermi gas. An experiment in an ultracold fermionic gas now shows how to control their properties with a tunable radio-frequency field.
- Observation of polarization density waves in SrTiO<sub>3</sub>Nature Physics, Published online: 07 April 2025; doi:10.1038/s41567-025-02874-0 Despite exhibiting ferroelectric features, SrTiO3 fails to display long-range polar order at low temperatures due to quantum fluctuations. An ultrafast X-ray diffraction experiment now probes polar dynamics of this material at the nanometre scale.
