面对日益更新发展的社会,我们迎来了一个新的科技时代,“超导”时代。“超导”已经悄然的走进我们的生活,通过对“超导”电性的理论研究及其应用的了解,我们可以让生活变得更精彩,把我们带入用电的新时代。因此它涉及电子的电荷、自旋和轨道之间它们与晶格之间十分强烈的耦合,电子与电子,电子与声子以及声子之间的互作用等等,需要用到强关联系统来研究。 In the face of the ever-changing society, we usher in a new era of technology, “superconducting” era. “Superconductivity” has quietly entered our life. Through the theoretical study of “superconductivity” and its application, we can make life more exciting and bring us into a new era of electricity use. So it involves the charge of the electron, the strong coupling between the spin and the orbit and the lattice, the interaction between the electron and the electron, the electron and the phonon and the phonon, etc., which need strong correlation system the study.
