The proposed analytical models for the modulation potential and the basis wave-function reflect the symmetry and the topology of the system allowing to get high accuracy results. The calculated dependencies of the electronic band structure versus magnetic field show two detached minibands in the region of low energies, while higher minibands manifest crossings and anticrossings. The existence of highly degenerate energy levels (miniband nodes) for certain values of magnetic field is revealed. The miniband nodes are preserved when taking into account the Coulomb interaction of the electrons. The interaction causes both an upward shift and broadening of minibands, while also shifting the nodes to higher magnetic fields. The miniband nodes have their signature in the magnetization of the electron gas and in the interminiband transitions. The number of electrons per a unite cell of the system has a strong impact on the current density distribution, magnetization and the oscillator strength.

In fiber–optic communication, implementing OAM modes offers an additional spatial multiplexing dimension, enabling significant capacity increases for communication system. To effectively utilize OAM modes as independent and stable transmission channels, various ring-core fibers are proposed and fabricated to match the annular intensity distribution of these modes. Among these designs, a series of non-zero dispersion-shifted ring-core fibers (NZDSRF) emerges as a promising approach for dispersion management in OAM-based transmission. By carefully engineering the dispersion characteristics of the fiber, NZDSRFs can minimize signal pulse broadening, making them more suitable for long-distance OAM multiplexing systems.

In this work, a quantum-informed local analogue model (QILAM) that maps these nonclassical optical responses onto a local dielectric film is presented. The primary advantage of this model lies in its compatibility with the highly efficient boundary element method (BEM), which includes retardation effects with relatively large particle sizes. Furthermore, the approach offers a unified framework that connects two important semiclassical theories: the generalized nonlocal optical response (GNOR) theory and the Feibelman d-parameters formalism. It is envisioned that QILAM can evolve into a multiscale electrodynamic tool for exploring nonclassical optical responses in diverse plasmonic structures in the future. This can be achieved by directly translating mesoscopic effects into observable phenomena, such as plasmon resonance energy shifts and linewidth broadening in the scattering spectrum.</p>","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793310","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}
