项目摘要
We have developed a theory of superconductivity due to the critical valence fluctuations, showing that the theory explains existing experimental results in a unified way. This implies that the critical valence fluctuations play the important role in Ce-and Yb-based heavy fermion metals. We found that the quantum critical valence transition exhibit non-Fermi liquid behaviors of new universality class which gives a basis of understanding unconventional non-Fermi liquid behaviors such as in YbRh_2Si_2 and.-YbAlB_4. It is a great success that the paradox of negative Meissner effect in odd-frequency superconductivity was solved, releasing its superconductivity from skeptical atmosphere in the community of strongly correlated electron systems.
由于临界价涨落,我们发展了超导理论,表明该理论以统一的方式解释了现有的实验结果。这意味着临界价态波动在Ce基和Yb基重费米子金属中起着重要作用。我们发现量子临界价态跃迁表现出新普适性类别的非费米液体行为,这为理解YbRh_2Si_2和.-YbAlB_4等非常规非费米液体行为奠定了基础。解决了奇频超导中负迈斯纳效应的悖论,将其超导性从强相关电子系统群的怀疑气氛中释放出来,这是一个巨大的成功。
