While plasmonic resonance offers a powerful platform for this purpose, the hot-electron injection and photothermal effects accompanying plasmon relaxation are inherently coupled, posing a critical challenge for their selective utilization. Here, we achieve active separation of plasmonic energy by constructing SiO2/Eu2O3/Ag and SiO2/Eu2O3/VO2/Ag heterostructures. In the direct-contact system, synergistic hot-electron injection and photothermal effects induce the Eu3+ crystal field distortion, driving the hypersensitive electric dipole transition to dominate over the magnetic dipole transition, thereby realizing wavelength-state storage with a luminescence contrast of 0.94. The introduction of a semiconducting VO2 interlayer acts as an electron barrier, blocking hot-electron injection while retaining the pure photothermal effect. This photothermal stimulation modulates the VO2/Eu2O3 interfacial defect states and V-3d electronic states, profoundly altering the Eu3+ excited-state dynamics (with the lifetime shortened from 67.79 to 1.97 μs), thereby enabling intensity-state storage. This dual-mode platform enables patterned recording alongside reversible self-erasure and nonvolatile operation. Our work offers a clear physical picture of diverting plasmonic energy channels toward low-energy, multidimensional optical storage.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"28 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221784","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}

In particular, we ask the following question: Could a resource-constrained learner/tester use interaction with a resource-unconstrained but untrusted party to solve a learning or testing problem more efficiently than they could without such an interaction? In this work, we answer this question both abstractly and for concrete problems, in two complementary ways: For a wide variety of scenarios, we prove that a resource-constrained learner cannot gain any advantage through classical interaction with an untrusted prover. As a special case, we show that for the vast majority of testing and learning problems in which quantum memory is a meaningful resource, a memory-constrained quantum algorithm cannot overcome its limitations via classical communication with a memory-unconstrained quantum prover. In contrast, when quantum communication is allowed, we construct a variety of interactive proof protocols, for specific learning and testing problems, which allow memory-constrained quantum verifiers to gain significant advantages through delegation to untrusted provers. These results highlight both the limitations and potential of delegating learning and testing problems to resource-rich but untrusted third parties.","PeriodicalId":20807,"journal":{"name":"Quantum","volume":"234 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Nonlinear wave mixing can relax this constraint by combining the directions of the driving fields. If the generated wavelength is longer than the driving wavelengths, intrinsic backward emission can become efficient. Here we exploit this regime using coherent Stokes Raman scattering to generate signal directly into the backward hemisphere. Simulations pinpoint high-numerical aperture geometries and polarization states that maximize backward emission, and experiments confirm backward signals from liquids and tissues with detected levels approaching the strength of forward-detected coherent Raman signals. Because the generated signal originates at the focus and remains refocusable, it enables coherent Raman microscopy with same-side confocal collection compatible with fibre coupling and spectrometers when transmission access is impractical. The approach is particularly relevant and beneficial for samples on opaque substrates, thick specimens, tissue biopsies and fibre- or spectrometer-based implementations.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"11 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218199","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}

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}
