A first-order, disorder-driven, superconductor–insulator phase transition is demonstrated. This is in contrast with the usually observed second-order transition and highlights the role of Coulomb interactions between preformed Cooper pairs.

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.

- Nature Physics, Published online: 03 January 2025; doi:10.1038/s41567-024-02700-z In strongly correlated systems, weak interactions can lead to the formation of correlated pairs of bosons with opposite momenta. Now, an experiment on ultracold bosons shows the breakdown of this effect in the strong interaction regime.

Now, an experiment with ultracold atoms shows signatures of hydrodynamic behaviour in a regime where length scales are comparable.

Experiments with rotating particles in intermediate Reynolds flow now harness a mostly unexplored inertial regime for synthetic active matter.
- Nature Physics, Published online: 20 December 2024; doi:10.1038/s41567-024-02702-x Topological terms arise naturally in gauge theories but have been difficult to implement in quantum simulators. Now, a tunable topological θ-angle is demonstrated with a cold-atom platform.
