Unified theory of phonon in solids with phase diagram of non-Debye anomalies
Nature Physics, Published online: 07 October 2025; doi:10.1038/s41567-025-03057-7
Van Hove singularities in crystals and the boson peak in glasses are both deviations from the Debye theory of phonons. A unified model for the vibrational density of states now shows when these two phenomena have distinct phononic origins.

How to build a long-lived qubit
Nature Physics, Published online: 06 October 2025; doi:10.1038/s41567-025-03044-y
Improvements in qubit performance are essential for the development of large-scale quantum computing devices. Sustained progress requires a broad approach combining physics, materials science, and engineering mindsets.

Terahertz excitation of collective dynamics of polar skyrmions over a broad temperature range
Nature Physics, Published online: 03 October 2025; doi:10.1038/s41567-025-03056-8
Terahertz control of polar skyrmions—topological textures of electric dipoles—is key for fast optoelectronics. Now, ultrafast excitation of polar skyrmions is achieved across two orders of magnitude of temperature in an oxide heterostructure.

Imaging isospin order in rhombohedral graphene reveals anisotropy in correlated states
Nature Physics, Published online: 03 October 2025; doi:10.1038/s41567-025-03036-y
The microscopic magnetic textures of isospin symmetry-broken phases in rhombohedral tetralayer graphene have been directly imaged. By probing spin orientation and magnetic anisotropy at ultra-low fields, key energy scales — the spin–orbit coupling and intervalley Hund’s exchange — have been extracted, shedding new light on the phase hierarchy in strongly correlated electron systems.

Radioactive ion beams for radiotherapy
Nature Physics, Published online: 02 October 2025; doi:10.1038/s41567-025-03038-w
Radiotherapy with charged particles is highly sensitive to uncertainties in their range. Now, radioactive ion beams offer increased precision and real-time imaging for tumour control while maintaining low toxicity to organs at risk.

Scattered waves reveal hidden objects
Nature Physics, Published online: 02 October 2025; doi:10.1038/s41567-025-03043-z
Imaging through opaque media is challenging. But through the chaos it is possible to discern unique fingerprints of the objects hidden within.

Detection and characterization of targets in complex media using fingerprint matrices
Nature Physics, Published online: 02 October 2025; doi:10.1038/s41567-025-03016-2
Imaging through complex media is challenging because scattering results in image blurring. By introducing a fingerprint operator and applying it to the measured reflection matrix, information on a target within a complex medium becomes accessible.
