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}

[J. High Energ. Phys. 2023, 232 (2023)] first found that the fidelity of quantum teleportation with a bipartite entangled resource state, completely determined by the fully entangled fraction (FEF) characterized by the maximal fidelity between the given quantum state and the set of maximally entangled states, can monotonically increase in Schwarzschild spacetime. The Hawking effect on the FEF of quantum states in tripartite systems is investigated. In this study, it is showed that the Hawking effect of a black hole may both decrease and increase the FEF in Schwarzschild spacetime. For an initial X-type state, it is found that the Hawking effect of the black hole has both positive and negative impacts on the FEF of Dirac fields, depending on the selection of initial states. For an initial W-like state, the Hawking effect of the black hole has only a positive impact on the FEF of Dirac fields, independent of the selection of initial states. These results provide an insightful view of quantum teleportation in multipartite systems under the influence of Hawking effects, from the perspective of quantum information and general relativity.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389443","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 scheme involves two microwave cavities with distinct quality factors that simultaneously couple to a magnon mode of a macroscopic yttrium-iron-garnet sphere via the magnetic-dipole interaction. It is demonstrated that both the bipartite and tripartite entanglement among the three modes will be generated due to Kerr nonlinearity, and the perfect one-way EPR steering will also be achieved between the cavity with higher quality factor and the magnon mode. Notably, this scheme differs from conventional protocols that produce asymmetric EPR steering by introducing additional unbalanced losses or noises; instead, it can generate and manipulate one-way EPR steering solely by adjusting the detuning between the magnon mode and the microwave drive field. It is also analyzed that the robustness of the entanglement and EPR steering against the dissipation of magnon and environmental temperature. The present scheme may provide a promising platform and an efficient quantum resource for quantum information processing.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389438","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}
