The trajectories of singularities are found to form two groups of nested spirals, with one originating from each dislocation. The number of spirals nested in each group is found to be equal to the topological charge of the dislocation from which it originates. The influence of the initial distance between dislocations on the trajectories of singularities is examined in detail, and the distinctive characteristics of this dependence are highlighted. The trajectory of the displacement of centroids of singularities from one group of nested spirals during the propagation for various topological charges is investigated. The results demonstrate that the higher the topological of the second dislocation is, the faster the centroid from the first dislocation will shift along the <math>\u0000 <semantics>\u0000 <mi>y</mi>\u0000 <annotation>$y$</annotation>\u0000 </semantics></math> axis during the propagation. This finding indicates that the trajectory of singularities displacement is not defined by the singularity itself, but rather by the background field, which correlates well with the hydrodynamic approach.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595519","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}

This conservation leads to a spin transport which becomes evident when light encounters a refractive index gradient, i.e., when it is reflected, refracted, or scattered. The phenomenon is so-called as the spin-orbit interaction (SOI) of light has paved the way to manipulate the light-matter interaction at the nanoscale and has remained the core of many recent studies. Particularly, the photonic spin Hall effect (PSHE) which is the microscopic spin splitting into circular polarization has given rise to novel applications, for example, precision metrology. The PSHE is well explored at planar interfaces, however much less attention is given to it when the optical potential gradient is of higher dimensionality, i.e., for nanoparticles. In this review, the theoretical description of the PSHE as well as the SOI in the scattering of light from nanoparticles are covered. Recent advances and trends in the PSHE in nanoparticles are reviewed. The review is concluded with suggestions for some novel directions in the field of PSHE of nanoparticles.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793830","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}

The AMCS is composed of a type I labyrinthine metamaterial in the outer ring, a six-channel spiral metamaterial in the middle ring, a type II labyrinthine metamaterial in the inner ring, and a porous acoustic-absorbing metamaterial in the inner inlay. The simulation results show that the average sound attenuation reaches 17 dB in the range of 0–5000 Hz due to the multilevel Fano resonance effect during the sound wave propagation process. Meanwhile, the sound field distribution law and the flow diagram also verify that the multilevel Fano resonance mechanism is the key factor causing broadband sound absorption. Then, the AMCS is fabricated by 3D printing, and the simulation results are verified by the acoustic experiment for AMCS cell. Additionally, to further enhance the overall sound attenuation in the railroad noise field, a simulation model of the combined train-track-AMCS sound barrier coupling is developed, and it is found that the AMCS type sound barrier can effectively block the propagation of wheel-rail noise from different angles, and it possesses a noise reduction of 20 dB in all frequency bands.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595444","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}

However, there are still some disagreements regarding the origin of the D-center, as well as a lack of sufficient understanding of the related optical transitions and carrier capture processes. In this work, based on first-principles calculations, the optoelectronic properties of boron-related point defects in 4H-SiC is systematically investigated, and the passivation of hydrogen on BC defects is also evaluated. The calculated 0/−1 transition levels of substitutional defect BC are very close to the activation energies of the D-center observed in experiments. Furthermore, the photoluminescence (PL) peak positions and non-radiative hole capture cross-section of BC defects calculated are all in good agreement with the experimental values of the D-center. This confirms that the substitutional defects BC are responsible for the D-center in 4H-SiC. These calculation results reveal that the hydrogen atom in 4H-SiC prefers to combine with the BC defects and to passivate the deep acceptor level within the bandgap in 4H-SiC by forming the BC-H complex. This work effectively identifies and passivates the D-center in 4H-SiC, providing valuable insights for improving the performance of various semiconductor materials affected by deep defects.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595626","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}

Single frequency (SF) and ultrafast lasers represent two types of highly coherent light sources, each with distinct time-frequency characteristics. The advent of novel technologies based on electro-optics and nonlinear optics has bridged the gap between these two types of lasers, enabling coherent conversion between them. This review examines several technologies that enable coherent conversion between SF and ultrafast lasers. The generation of ultrafast pulses by modulation of an SF laser, covering both electro-optic modulation (EOM) and optic-optic modulation (OOM) is discussed. With respect to Kerr soliton generation by SF laser-induced parametric frequency conversion, schemes with and without resonator structure are compared and discussed. The extraction of a single comb line from an ultrafast laser using stimulated Brillouin scattering is also presented. The advent of new technologies using all-polarization-maintaining fiber structures has made fiber Brillouin amplification a practical and robust solution for single comb line extraction. These coherent lasers with customizable time and frequency characteristics are poised to become essential building blocks in future photonic technologies.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793751","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}
