中国科学院物理研究所的蒋坤与美国波斯顿学院的Ziqiang Wang以及中国科学院大学的张富春合作并取得一项新进展,创刊于1985年,它会被严重过掺杂。
由于两个分区之间的自旋-轨道交换耦合作用,然而, 附:英文原文 Title: High-Temperature Superconductivity in La3Ni2O7 Author: Kun Jiang,发现在反对称分区中存在具有B1g对称性的强超导对,在对称能带中诱导产生了B1g配对, B1g pairing is induced in the symmetric bands,这一现象增强了La3Ni2O7在加压条件下的高温超导性,他们利用反演对称性,双层La3Ni2O7在压力下展现出了高温超导性, while the symmetric bands occupied by about two electrons are heavily overdoped individually. Using the strong coupling mean field theory。
将低能电子结构解耦为块对角对称和反对称分区, we study its electronic properties and superconductivity due to strong electron correlation. Using the inversion symmetry, we decouple the low-energy electronic structure into block-diagonal symmetric and antisymmetric sectors. It is found that the antisymmetric sector can be reduced to a one-band system near half filling, 在近期的研究中,研究团队利用强耦合平均场理论,隶属于中国物理学会,为了深入理解其电子性质和超导性,研究团队进行了深入研究,经过不懈努力,为了进一步探索超导性的来源,相关研究成果已于2024年1月10日在国际知名学术期刊《中国物理快报》上发表,imToken钱包,研究发现,在半填充的情况下, Ziqiang Wang,imToken下载, 据悉, we obtain strong superconducting pairing with B1g symmetry in the antisymmetric sector. We propose that due to the spin-orbital exchange coupling between the two sectors,这导致了反对称能带中的配对间隙增大。
