In its aperture‐type implementation, the local field is collected through a sub‐wavelength aperture and an optical fiber. The choice of this fiber imposes an inherent trade‐off between signal strength and phase fidelity. Single‐mode fiber probes maintain phase fidelity but suffer from low signal intensity, whereas multimode fiber probes offer higher throughput but introduce severe phase distortions. Here, we present phase‐conjugation interferometric NSOM (PCI‐NSOM), which overcomes this limitation. The output field of the multimode fiber is measured by off‐axis holography, and its phase conjugate is displayed on a spatial light modulator, converting the scrambled speckle into a planar wavefront that focuses to a single point in Fourier space. At the focal pixel of the detector, the correction enhances the intensity by up to ∼165‐fold. We demonstrate PCI‐NSOM by imaging surface plasmon polaritons on a gold grating, obtaining accurate phase maps where uncorrected multimode collection fails through modal dispersion and single‐mode collection through a low signal‐to‐noise ratio. PCI‐NSOM thus provides a practical route to high‐sensitivity phase‐resolved nanoscale optical characterization.","PeriodicalId":19027,"journal":{"name":"Nanophotonics","volume":"6 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208934","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}

The first-order action already singles out natural canonical pairs: the auxiliary Lorentz scalars are conjugate to the spatial connection and zweibein. An extended Dirac–Bergmann embedding isolates an auxiliary second-class sector whose elimination recovers the canonical structure encoded in the first-order action and leaves the first-class constraints generating the local gauge symmetries. An independent Faddeev–Jackiw reduction yields the same reduced brackets. The Katanaev/Poisson–Sigma Casimir is then recovered, up to normalization, directly from the reduced Dirac–Bergmann first-class constraint ideal, before imposing any gauge condition. This identifies the Casimir as a global label of the reduced canonical sectors and supplies a convenient parameter for the torsionful branch. The independent constant normalization of the Killing time is displayed explicitly and then fixed to the local convention <span>(A=1)</span>. In this convention the Casimir-normalized radial field does not coincide with the metric Killing norm: the diagonal representative satisfies <span>(NB=e^{4beta r})</span>. Consequently, torsion modifies the Killing temperature in the chosen Killing-time normalization, while the horizon entropy retains its standard two-dimensional dilaton value and the Casimir-normalized first law holds.</p></div>","PeriodicalId":578,"journal":{"name":"General Relativity and Gravitation","volume":"58 10","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

First, using the truncated Painlevé expansion method, we reveal the relationship among the nonlinear BKP equation, the trilinear BKP equation, and the linear free Schrödinger equations. Subsequently, a special family of generalized solutions is constructed from the solutions to these linear free Schrödinger equations. Second, using the Fourier transform and the generalized linear superposition principle, we derive the <i>N</i>-lump soliton solutions for the (2+1)-dimensional BKP equation, which take the form of a special class of generalized Schur polynomials. Furthermore, we focus on the anomalous interactions of the 2-lump and 3-lump soliton solutions. Through a parameter region analysis, mutually repulsive interactions, fusion–fission interactions, exchange lump soliton interactions, and lump-soliton rotation induced by anomalous two-lump interactions are revealed. In particular, the anomalous interaction patterns of 2- and 3-lump soliton solutions are systematically classified by means of the parameters <span>(D)</span> and <span>(M)</span>. Detailed theoretical analysis and graphical illustrations are presented to interpret these anomalous interaction phenomena. Finally, we explore the long-time asymptotic properties of the <i>N</i>-lump soliton solutions and characterize their superimposed structures composed of <i>N</i> individual single-lump solitons. These results lay a theoretical foundation for understanding the rich dynamics of high-dimensional nonlinear localized waves.</p></div>","PeriodicalId":597,"journal":{"name":"International Journal of Theoretical Physics","volume":"65 11","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
