- Terahertz excitation of collective dynamics of polar skyrmions over a broad temperature range
- Imaging isospin order in rhombohedral graphene reveals anisotropy in correlated statesNature 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.
- Scattered waves reveal hidden objectsNature 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 matricesNature 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.
- Radioactive ion beams for radiotherapyNature 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.
- Isospin magnetic texture and intervalley exchange interaction in rhombohedral tetralayer grapheneNature Physics, Published online: 02 October 2025; doi:10.1038/s41567-025-03035-z Hund’s exchange interaction energy in two-dimensional materials is challenging to extract from experiments. Now, this is achieved in rhombohedral graphene, which allows an estimate of the interactions that drive the variety of correlated states in this material.
- Impact of low-energy spin fluctuations on the strange metal in a cuprate superconductorNature Physics, Published online: 30 September 2025; doi:10.1038/s41567-025-03034-0 The underlying physics of the strange metal phase observed in many strongly correlated materials is not well understood. Now, evidence emerges that antiferromagnetic spin fluctuations play an important role.
- Gate-tunable double-dome superconductivity in twisted trilayer grapheneNature Physics, Published online: 30 September 2025; doi:10.1038/s41567-025-03040-2 Two regions of superconductivity are observed in the phase diagram of magic-angle twisted trilayer graphene. This may yield insight into the superconducting mechanism in moiré materials.
