The Kondo model (sometimes referred to as the s-d model) is a model for a single localized quantum impurity coupled to a large reservoir of delocalized and noninteracting electrons. The …

因此, Kondo效应, 或者更一般的说, Kondo物理, 指的就是 多电子体系 在稀磁合金中出现的磁性杂质-非磁性宿主金属之间的对抗; 而在零温的费米面附近, 这一对抗导致的结果是强关联的. 这 …

所谓Kodo effect是日本科学家近藤淳老先生在解释低温下磁性杂质原子掺杂正常金属带来的电阻极小值这种奇异行为所做的工作。 这里，我仅仅唯象地，以自己的认识简述一下Kondo问题的基 …

The SIAM and the Kondo model belong to the class of quantum impurity models (QIM) which are defined by a finite number of local degrees of freedom, which are coupled to one or more …
