Abstract
A nonperturbative proof of Luttinger's theorem, based on a topological argument, is given for Fermi liquids in arbitrary dimensions. Application to the Kondo lattice shows that even completely localized spins contribute to the Fermi sea volume as electrons, whenever the system can be described as a Fermi liquid.
摘要
基于拓扑论证，给出了任意维度费米液体中卢廷格定理的非微扰证明。应用于近藤晶格表明，只要系统可描述为费米液体，即使是完全局域化的自旋也会像电子一样对费米海体积有贡献。
