However, tailoring their emission characteristics beyond the intrinsically narrow excitonic linewidth remains a key challenge. Here, we report a hybrid microcavity platform consisting of a WS<sub>2</sub> monolayer coupled to polystyrene microspheres (PS-MSs) on a gold substrate under continuous-wave excitation. In this system, light emission can be tailored through the interplay between cavity-enhanced local electromagnetic fields and photoinduced changes in the microcavity optical response. At low excitation powers, the emission evolves from neutral-exciton-dominated to trion-dominated photoluminescence with a continuously tunable intensity ratio, reflecting changes in the relative exciton-trion contributions under laser excitation. At higher excitation powers, the system transitions to a broadband-emission regime, which is associated with irradiation-induced modifications of the microcavity optical properties and is further enhanced by the cavity configuration. The incorporation of the WS<sub>2</sub> monolayer is correlated with enhanced broadband emission and improved performance under continuous-wave excitation, while also influencing the interfacial excitonic emission behavior. Furthermore, extending this approach to multiple-microsphere assemblies enables larger-area broadband emission, suggesting the potential scalability of this strategy toward planar white-light sources. These results establish a simple strategy for tailoring light emission in hybrid microcavities and provide insights into cavity-enhanced optical processes in coupled two-dimensional material-polymer systems, with potential applications in integrated photonic devices and broadband light sources.</p></div>","PeriodicalId":774,"journal":{"name":"Science China Physics, Mechanics & Astronomy","volume":"69 12","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189196","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}

While general relativity allows only two tensor modes (+, ×), GQFT additionally favors a massless breathing scalar mode, providing a compelling yet largely unexplored observational target for testing quantum gravity. The central challenge is therefore to assess, in a mission-agnostic manner, how well future space-based interferometers can disentangle and detect these tensor and scalar polarization components across the sky. In this work, we develop a model-independent response formalism for LISA- and Taiji-like detectors by incorporating first-order orbital dynamics in the solar system barycenter frame. This framework yields three key observational consequences: (i) characteristic interference patterns between tensor and scalar modes, (ii) a generalized, model-independent response function for the breathing mode, and (iii) sky-position-dependent strategies that optimize detectability. We further translate the formalism into comprehensive polarization maps that provide complete sky coverage and remain fully compatible with existing mission designs, thereby circumventing the need for challenging direct breathing-mode measurements. Overall, our results deliver practical tools for future data analysis and establish a systematic avenue to test fundamental theories of gravity through their GW polarization fingerprints.</p></div>","PeriodicalId":774,"journal":{"name":"Science China Physics, Mechanics & Astronomy","volume":"69 11","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132894","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 photosynthetic light-harvesting complexes, excitation energy transfer can proceed with remarkably high efficiency. With advances in experimental techniques, two-dimensional electronic spectroscopy can reveal dynamic processes such as coherence and coupling within a system, and it plays an important role in studying energy transfer in photosynthesis. On the theory side, methods such as the generalized Bloch-Redfield theory and the hierarchical equations of motion are used to model photosynthetic systems. Quantum simulation has also emerged as a complementary route for investigating photosynthetic dynamics, with implementations on multiple experimental platforms. In recent years, a series of studies has introduced quantum coherence into artificial systems to enhance energy transfer efficiency, laying the groundwork for the design of coherent devices with efficient energy transport. Birds are thought to sense direction by exploiting the weak geomagnetic field through spin-dependent chemical reactions. Theoretical frameworks for animal navigation include magnetite-based mechanisms, magnetoreceptor genes, and the radical-pair mechanism. Quantum simulation of magnetoreception-related spin dynamics has likewise progressed across multiple platforms. Inspired by animal navigation, diverse quantum effects have been applied to improve sensing and to support navigation tasks.

Conventional methods often require parameterized forms of FFs and additional scale evolution according to the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution equations. We introduce a novel approach to determining parton FFs using a physics-informed neural network (PINN). Unlike traditional methods, our approach does not require prior parameterized forms and directly integrates the DGLAP evolution equations into the neural network architecture, allowing the FFs to automatically satisfy these equations. We present new sets of parton FFs extracted from hadron spectra in electron-positron annihilation processes at next-to-leading order (NLO) in pQCD using this new technique. To validate our approach, we calculate charged hadron spectra in proton-(anti)proton collisions using the extracted FFs and demonstrate that the results align well with experimental data across a large range of colliding energies (<span>(sqrt{s})</span> = 130, 200, 500, 630, 900, 1800, 2760, 5020, 5440, and 7000 GeV). Our findings indicate that the PINN method not only simplifies the extraction process but also enhances the universal applicability of FFs across different energy scales. By eliminating the need for parameterized forms and additional DGLAP evolution, our approach represents a significant step forward toward fast and accurate extractions of non-perturbative quantities such as parton fragmentation functions and parton distribution functions.</p></div>","PeriodicalId":774,"journal":{"name":"Science China Physics, Mechanics & Astronomy","volume":"69 11","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132817","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}
