Our study combines mean-field calculation in the superconducting phase with pairing instability analysis of the normal state, incorporating the next-nearest-neighbor hopping in the single-particle dispersion relation. We demonstrate that the two types of altermagnetism have markedly different impacts on the stabilization of FFLO states. Specifically, <span>(d_{xy})</span>-wave altermagnetism supports FFLO superconductivity over a broad parameter regime at low fillings, whereas <span>(d_{x^{2}-y^{2}})</span>-wave altermagnetism only induces FFLO pairing in a narrow range at high fillings. Furthermore, we find that the presence of a Van Hove singularity in the density of states tends to suppress FFLO superconductivity.

Given the current capabilities of artificial intelligence, machine learning in this area typically serves less as a stand-alone predictor but more as a practical tool for guiding exploration within complex design spaces. After briefly reviewing key developments, this perspective adopts a case-driven approach and organizes machine learning applications in this field into three recurring levels: macroscopic compositional design, where the main challenge is combinatorial complexity; microscopic electronic and structural responses, where properties depend sensitively on subtle local variations; and dynamic or time-dependent processes, where behavior is governed by pathways or sequential signals. Representative examples show how each level benefits from different methodological choices and practical tools, ranging from data-driven screening and optimization to physics-aware surrogates and pathway-based or sequential learning. Examining these cases in parallel allows us to extract transferable principles, including physically informed feature design, data efficiency, and uncertainty awareness, while also clarifying the practical limitations of current approaches.</p></div>","PeriodicalId":100007,"journal":{"name":"AAPPS Bulletin","volume":"36 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43673-026-00185-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606840","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}

Here, we propose a scheme termed semantic quantum secure direct communication (QSDC), which is a novel paradigm integrating semantic communication with QSDC to realize highly efficient, task-oriented, and intrinsically secure information transmission. In semantic QSDC, meaningful semantic content is directly encoded into quantum states, whereby the fundamental laws of quantum physics guarantee inherent eavesdropping-detection capability and information-theoretic security. By harnessing semantic compression and artificial intelligence–assisted encoding strategies, this approach surpasses the intrinsic rate constraints of conventional QSDC. Simulation results show that semantic QSDC can surpass the Shannonian mutual information bound compared with conventional QSDC systems and demonstrate its potential to break through the linear rate-transmittance bound of quantum communication.
