We derive multi-breather wave solutions. They present the oblique breathers, homoclinic orbits and their mixtures under two parameter constraints. We also obtain the general high-order lump solutions by employing the Schur polynomials. When internal parameters a2m+1 are large, the patterns display the polygons containing lower-order lump pattern in the central region together with possible multiple fundamental lumps in the outer region. When time t is large, two types of lump patterns are presented by considering the prediction solutions. The first type of lump patterns contain fundamental lumps with triangular shapes. The second type of lump patterns contain fundamental lumps with non-triangular shapes in the outer region, together with possible fundamental lumps with triangular shapes in the inner region. Furthermore, we construct the semi-rational solutions to exhibit the fascinating processes of fusion and fission between lumps and line solitons. These solutions should be of great interest in a variety of high-dimensional multi-component systems.","PeriodicalId":17304,"journal":{"name":"Journal of the Physical Society of Japan","volume":"15 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139646074","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}

We have performed carrier tuning by chemical substitution to Ni sites to bring the electronic states of Ni closer to that of Cu in superconducting cuprates. We aim to substitute the specific Ni sites for carrier tuning without disturbing the NiO2 planes. In this study, we perform neutron powder diffraction experiments for the Pr4Ni3−xCoxO8 samples with doping Co for Ni sites to investigate the dopant distribution among the Ni sites. Rietveld analysis showed a tendency to preferentially occupy specific Ni sites when the doping level was low, but this is not the case for higher doping levels. We also analyzed the oxygen deficiency and found no oxygen deficiency in the NiO2 planes with lower chemical substitutions, indicating that the relatively undisturbed conduction planes were maintained. Finally, we discuss the effects of Co doping into NiO2 planes for the physical properties of R4Ni3O8.","PeriodicalId":17304,"journal":{"name":"Journal of the Physical Society of Japan","volume":"397 2 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139587971","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}

In NaSn2As2, a broad 75As NQR spectrum indicates a large charge distribution at the As site, and a broad 119Sn NMR spectrum indicates a distributed local density of states (DOS) at the Sn site. Almost the same level of microscopic disorder in the electronic state is also found at the Sn site in Na1−xSn2P2 as well. These results clearly indicate the presence of a local atomic disorder in these superconductors. We have also measured the nuclear spin–lattice relaxation rate 1/T1 to gain insight into the partial DOS at each site. Our NMR/NQR results are consistent with previous band calculations, indicating that Na deficiency results in an increase in the DOS at the Fermi energy (EF) due to the decrease in EF. The agreement between the experimental and band calculation results makes it more plausible that the increase in the Tc of Na1−xSn2P is due to the increase in the DOS at EF caused by the Na deficiency. This study thus demonstrates that NMR/NQR measurements can be a very effective tool in revealing the local electronic structure of materials by comparing experimental results with theoretical band calculations.","PeriodicalId":17304,"journal":{"name":"Journal of the Physical Society of Japan","volume":"213 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139555116","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-crystal LaO0.5F0.5BiS2 exhibits filamentary superconductivity with Tc of approximately 3 K. We found that the partial substitution of Bi with Sn in LaO0.5F0.5BiS2 induces a structural phase transition from the P4/nmm to P21/m structure. Bulk superconductivity with Tc of approximately 6 K emerged near this structural phase transition. We also observed filamentary superconductivity with Tc of approximately 8 K, which was approximately three times higher than that of the unsubstituted sample.
