In cuprate high-temperature superconductors, no equivalent relationship between critical temperature and electron–boson coupling has been identified. Here we highlight such a link with electrons scattering off commensurate antiferromagnetic spin fluctuations of variable strength. We use d.c. resistivity and high-field magnetoresistance to extract the scattering rate in electron-doped La2−xCexCuO4 as a function of doping. We reveal a highly anisotropic inelastic component to the scattering rate whose magnitude diminishes markedly as doping increases. The correlation we highlight between the strength of scattering and the critical temperature then identifies low-energy spin fluctuations as the primary pairing glue in electron-doped cuprates. The contrasting magnetotransport behaviour in hole-doped cuprates suggests that the higher critical temperature in those materials cannot be attributed solely to an increase in the coupling strength to the antiferromagnetic fluctuations. The success in modelling La2−xCexCuO4 reinforces the notion that resolving the origin of high-temperature superconductivity in hole-doped cuprates may require more than a simple extension of the Bardeen–Cooper–Schrieffer theory.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"33 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their poor photon budget requires long exposure times, preventing faithful visualization of rapid physiological processes, especially in three dimensions. To overcome this barrier, we developed a Fourier light field microscope coupled with deep-learning-based reconstruction that achieves subsecond volumetric bioluminescence imaging, enabling direct recovery of 3D volumes from photon-limited measurements while suppressing reconstruction noise. This approach substantially mitigates the speed–resolution trade-off of conventional light field methods and bypasses the need for slow classical deconvolution priors on the depth-dependent point-spread function. We evaluate its performance by imaging 3D calcium activity in muscles and neurons of freely moving Caenorhabditis elegans and by quantifying cell dynamics within stem-cell-derived spheroids using fluorescenti acquired with fluorescence and bioluminescence contrast. Together, these results establish our framework as a practical tool for dynamic, volumetric studies of living systems.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"22 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The device exhibits a responsivity of 1.73 × 104 A/W, a detectivity above 1014 Jones, and a millisecond response time, outperforming most previously reported photoelectrochemical-type and solid-state bipolar photodetectors in terms of combined sensitivity, speed, and operational simplicity. Benefiting from the electrically programmable bipolar response, the phototransistor further realizes fast XOR logic functionality, enabling encrypted text communication and image encryption/decryption under solar-blind ultraviolet illumination.

In condensed matter, one of its most striking manifestations is the skyrmion Hall effect, where skyrmions—emergent spin configurations characterized by a conserved topological charge—acquire a transverse velocity under driving. Recent advances have revealed that chiral liquid crystals host a wide variety of topological solitons, including torons and skyrmion tubes. Here we show that such solitons exhibit a Hall-like response under shear flow, undergoing a transverse drift away from the shear direction. Our theoretical analysis predicts a weak net transverse mass flow whose magnitude scales as the cube of the shear rate. However, tracer-particle experiments and numerical simulations show that the solitons do not behave as passive tracers of this flow: their transverse motion is much stronger, and in simulations, it occurs opposite to the net transverse mass current. A liquid-crystal analogue of the Thiele equation provides a simple physical framework that highlights the central role of flow vorticity in the effect. These results establish a liquid-crystal analogue of the skyrmion Hall effect and open pathways for microfluidic technologies that exploit soft topological solitons as functional building blocks.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"12 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we propose and experimentally demonstrate that the transient coherent state (TCS)—occurring during the build-up of laser signals from amplified spontaneous emission in a non-equilibrium long-fibre laser—can be harnessed by periodically resetting the pump power. Using a Fourier-domain mode-locked (FDML) laser as a model, we show that an FDML laser operating in the TCS achieves an instantaneous linewidth at the kilohertz level. This represents a seven-orders-of-magnitude improvement over conventional FDML lasers. Furthermore, the residual phase jitter within the TCS can serve as an internal reference for self-regulation. By leveraging the unique combination of transient coherence and long-term chaos, we demonstrate a novel hybrid light detection and ranging scheme that features micrometre-scale resolution and a kilometre-scale measurable range. Finally, we apply the TCS concept to mitigate multi-longitudinal-mode operation in a self-injection-locked distributed-feedback laser, demonstrating that the TCS is equally valuable for lasers with long-term stable states.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"73 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
