A concept of flow impedance is introduced to model edge confinement of plasmas in tokamak and stellarator. The core confinement improvement is largely due to effective core heating profile, and direct ion heating with PNB system is favorable compared to electron heating in generation of sufficient α-power essential for sustaining the ignition state. Validation of transition physics of sustained ignition state from external to internal α-heating is critical for design of the next step magnetic fusion device. The most probable path for a compact ignition test device in magnetic fusion is suggested. The device size and expected performance of a tokamak plasma are projected based on critical review of experimental data of magnetic fusion research accumulated for half a century such as τE scaling laws and niτETi data. A tokamak plasma, Vp ~ 240 m3, equipped with direct ion heating system that can yield fusion power of ~ 220 MW (i.e., α-power up to ~ 45 MW) may be sufficient to test ignition state and transition physics.

While near-field coupling facilitates this paradigm shift, it imposes inherent constraints: the exponential decay of coupling strength fundamentally limits transfer distance to short-to-mid ranges, and complex power delivery pathways—exemplified by robotic arms—necessitate relay coils configured in domino-like arrays. Conventional domino architectures, however, suffer from significant drawbacks including detrimental frequency splitting due to multi-coil near-field coupling, exacerbated system losses under load, and an inherent lack of precise spatial control over energy delivery. To overcome these limitations, we introduce a customized WPT paradigm based on a one-dimensional non-Hermitian chain with engineered iso-spectral modulation. Through precise control of inter-resonator coupling strengths following a parabolic profile, we achieve an equally spaced eigenvalue spectrum. Crucially, frequency-selective excitation enables deterministic and customized energy localization at predetermined sites within the chain. This approach not only provides a novel platform for developing advanced WPT systems, particularly for simultaneous multi-target energy delivery, but also deepens the fundamental understanding of complex energy transfer dynamics governed by tailored coupling and non-Hermitian physics.</div>","PeriodicalId":100007,"journal":{"name":"AAPPS Bulletin","volume":"35 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43673-025-00166-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144904972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Infinite-layer (IL) cuprates, featuring a CuO2-terminated surface, emerge as optimal systems for this investigation. Leveraging controllable growth via molecular beam epitaxy, both electron- and hole-doped IL cuprates are realized, with surface structure and c-axis length serving as distinctive markers. A consistent pattern in the Mott transition is established, revealing that doping merely shifts the Fermi level without inducing changes in the Mott band structure, thereby suggesting a self-modulation doping scenario. Furthermore, the identification of a nodeless superconducting gap in the CuO2 planes challenges conventional notions derived from charge reservoir layers, advocating for a quantum well interpretation of cuprate superconductivity. This review sheds light on the distinct roles played by CuO2 layers and charge reservoir layers, promising a more profound comprehension of cuprate superconductivity through the lens of the CuO2 surface.</div>","PeriodicalId":100007,"journal":{"name":"AAPPS Bulletin","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43673-025-00152-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
