论文摘要
长期以来，富含灯笼氢的材料一直被认为是凝结物理学中具有高温超导性能的候选物质之一，并引起了极大的兴趣。试图研究富含兰谷氢材料的不同组合物的作用，近年来进行了预测和实验研究，表明诸如LAH 10，CEH 9和LAH 16的物质表现出150-250 GPA之间的极高的超导温度。研究人员特别指出，在这些材料中，费米水平的F特征增加会导致超导温度的升高。在这里，我们进一步详细阐述了这些物质中灯笼与氢的比率的影响，目的是通过比较使用DMFT方法的多种含量富含灯笼氢的材料，使这些极端情况下的超水的研究更加清晰，并为以后的结构预测和材料性质研究提供了想法。
Lanthanide hydrogen-rich materials have long been considered as one of the candidates with high-temperature superconducting properties in condensed matter physics, and have attracted great interest. Attempts to investigate the effects of different compositions of lanthanide hydrogen-rich materials are ongoing, with predictions and experimental studies in recent years having shown that substances such as LaH 10 , CeH 9 , and LaH 16 exhibit extremely high superconducting temperatures between 150-250 GPa. In particular, researchers have noted that in those materials an increase in the f character at the Fermi level leads to an increase in the superconducting temperature. Here, we further elaborate on the effect of the ratios of lanthanide to hydrogen in these substances with the aim to bring more clarity to the study of superhydrides in these extreme cases by comparing a variety of lanthanide hydrogen-rich materials with different ratios using the DMFT method, and provide ideas for later structural predictions and material property studies.
