Here we introduce Mie‐void metasurfaces operating in transmission, implemented using the silicon‐rich nitride (SRN) platform for visible‐range operation. We show that this transition is not a simple change in geometry: placing the voids in a finite film on a substrate introduces slab‐guided and Fabry–Pérot‐like contributions that hybridize with the underlying Mie‐void response. Rigorous coupled‐wave analysis shows that the dominant spectral transformation arises from replacing the semi‐infinite host with a finite SRN film, while the substrate acts as a secondary perturbation. Thickness‐dependent dispersion maps reveal an avoided crossing between interacting modes, identifying film thickness as a clean parameter for tracking the coupled modal evolution. Experimentally, we demonstrate depth‐dependent transmission spectra in good agreement with simulation, and realize visible structural colors and spatially encoded transmitted‐light patterns within a single metasurface architecture. These results establish transmission‐mode Mie‐void metasurfaces as a viable inverse‐dielectric platform for transmissive spectral filtering, optical encoding, and display‐oriented photonic elements.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"15 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149198998","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}

However, the limited number of observed core-collapse supernovae events makes it challenging to build robust data-driven models. The generation of synthetic gravitational wave signals from core-collapse supernovae can therefore provide a valuable tool for data augmentation in machine learning pipelines, particularly for the training and testing of detection and parameter estimation algorithms. Although recent efforts have explored the use of generative models to synthesize waveform-like data, existing approaches lack the ability to condition outputs on specific astrophysical parameters. To address this, we propose a model capable of generating gravitational wave signals conditioned on astrophysical parameters of core-collapse supernovae rotation. The proposed conditional derivative generative adversarial network is trained on the Richers et al. catalog, which contains 1,824 simulated time-series gravitational wave waveforms and their corresponding physical parameters. Quantitative evaluation using time-domain similarity and distributional metrics shows that the generated signals reproduce the key statistical and morphological features of the original dataset. This work introduces a conditional generative framework for rotating core-collapse supernovae gravitational wave signals, that enables fast, low-cost data augmentation and parameterized modeling, improving ML-based detection and parameter estimation.&#xD;","PeriodicalId":10282,"journal":{"name":"Classical and Quantum Gravity","volume":"10 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 investigate multimode exciton–photon coupling in visible semiconductor waveguides supporting several transverse electric modes. Using rigorous coupled-wave analysis combined with a coupled-oscillator model, we show that the photonic band structure can be engineered across a range of regimes, from conventional multimode strong coupling to the superstrong coupling regime, where the Rabi coupling becomes comparable to the spacing between adjacent photonic modes. In the latter regime, hybridization between orthogonal electromagnetic modes is enabled by restricting the active material to a subregion of the mode volume where the photonic modes exhibit strong mutual overlap. This breaking of the orthogonality leads to polaritonic branches whose composition can be tuned among several photonic modes and the exciton. We demonstrate that small shifts of the exciton resonance produce pronounced changes in the propagation constants of different polariton branches, enabling exciton-controlled phase modulation through modal interference and, in the superstrong coupling regime, direct modal switching across a continuous S-shaped dispersion. The resulting figures of merit predict π phase shifts for exciton energy shifts of only a few meV over propagation lengths of tens of micrometers, while larger shifts are still required for mode switching. These results establish multimode waveguide polaritons as a versatile platform spanning multiple coupling regimes, for compact phase and intensity control in integrated photonic architectures.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"482 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149210032","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}

Our results are obtained from an interplay of world-sheet semiclassical quantization methods and target space low energy effective ones. The Hagedorn temperature is given as an expansion in the inverse (large) ’t Hooft coupling limit. Working to quadratic order in the fluctuations, the world-sheet analysis provides the leading, the next-to-leading and part of the next-to-next-to leading order terms. In particular, it captures the NNLO log 2 terms which are due to the contributions of non-zero modes to the zero-point energy. These modes are not accounted for by the effective approach, within which they have to be included by hand using suitable educated guesses. On the other hand, the effective methods allow to compute in a relatively easy way the missing NNLO pieces (and even further subleading corrections), which could be accounted for from the world-sheet approach only working at quartic (or higher) order in the fluctuations. We present general results and several examples in various dimensions, including both confining models and conformal field theories on spheres (such as ( mathcal{N} ) = 4 SYM and ABJM) dual to string theories on global AdS spaces.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 10","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP10(2026)182.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider Higgs scattering in the unbroken phase of electroweak symmetry. Treating the final state as a momentum-isospin bipartite system, we obtain von Neumann and linear entropies to quantify momentum-isospin correlation. From the momentum reduced state, we calculate the concurrence, which measures the entanglement between the two isospins. Both quantities are set by the isospin singlet and triplet scattering amplitudes, and hence by the Wilson coefficients of the dimension-6 and dimension-8 Higgs operators. We find that the von Neumann entropy grows as a function of the total energy in SMEFT as compared to the SM case, but it undergoes a cancellation in the medium energy below the cut-off scale due to the interference effects between the dimension-4 and dimension-8 operators, in particular, when the effective interactions stem dominantly from a massive graviton. Assuming the dominance of dimension-8 operators, we find the conditions for entanglement suppression/generation in the forward or backward scatterings or across all the kinematics. We also show the correlations between the entanglement suppression and the positivity bounds in the forward limit.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 10","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP10(2026)191.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
