摘要

我们研究了近藤晶格模型中磁极子的形成。计算是在键粒子形式主义框架内完成的。我们证明，准粒子对应于空间范围取决于 k 的自旋极子。极子的形成导致带状结构重元素部分的有效质量显著增强。

Magnetic polarons in the Kondo lattice

We investigate the formation of magnetic polarons in the Kondo lattice model. Calculations are done in the framework of the bond particle formalism. We show that the quasiparticles correspond to spin polarons with a

k

-dependent spatial extent. Polaron formation leads to a significant enhancement of the effective mass in the heavy parts of the band structure.
