Strong photoexcitation of phonons in a crystal can lead to a nonlinear response. Now it is shown that this breakdown of linearity can be overcome by the application of well-timed photoexcitation pulses in WTe2.

- Coherent phonon control beyond amplitude saturation in a sliding ferroelectric
- Superconductivity and ferroelectric orbital magnetism in semimetallic rhombohedral hexalayer grapheneNature Physics, Published online: 21 October 2026; doi:10.1038/s41567-026-03443-9 The semimetallic regime in rhombohedral graphene has not been extensively explored. Now, correlated insulators, superconductivity and multiferroic orbital magnetic order are demonstrated in semimetallic rhombohedral hexalayer graphene.
- Light-induced asymmetric pseudogap below the critical temperature in cupratesNature Physics, Published online: 20 October 2026; doi:10.1038/s41567-026-03446-6 How superconductivity relates to the pseudogap in cuprates remains unclear. Now, time-resolved photoemission measurements show a light-induced pseudogap-like state below critical temperature, revealing a dynamic interplay with superconductivity.
- Fibres and glasses are competing material states in protein condensationNature Physics, Published online: 20 October 2026; doi:10.1038/s41567-026-03415-z Fibres are thought to emerge from a dense protein condensate ageing into a glassy state. It is now shown that protein fibres and glassy condensates may result from two competing ageing pathways.
- Evidence for spin-fluctuation-mediated superconductivity in electron-doped cupratesNature Physics, Published online: 19 October 2026; doi:10.1038/s41567-026-03454-6 The mechanism for superconductivity in cuprates is still not known. Now, the observation of a relationship between the critical temperature and strength of coupling between electrons and spin fluctuations suggests the latter as a prime candidate.
- A liquid-crystal analogue of the skyrmion Hall effectNature Physics, Published online: 19 October 2026; doi:10.1038/s41567-026-03379-0 Magnetic skyrmions are known to exhibit a Hall effect in the presence of an electric current. Now it is shown that liquid-crystal solitons also exhibit a Hall-like drift under shear flow.
- The extraction of work from hidden degrees of freedomNature Physics, Published online: 16 October 2026; doi:10.1038/s41567-026-03442-w According to the laws of thermodynamics, information can be converted into energy. An information engine that harnesses environmental memory and exhibits non-Markovian dynamics has now been realized in experiments.
- Cavity-less Brillouin strong coupling in a solid-state continuous systemNature Physics, Published online: 16 October 2026; doi:10.1038/s41567-026-03458-2 Strong coupling between light and matter is typically realized in resonators. Now it is shown that this can happen in a cavity-less waveguide scenario in which the light passes through only once.
