标题： Holographic mean field theory and Kondo lattice

摘要： 我们首先通过引入Kondo凝聚态来研究Kondo晶格的非相对论场理论模型，其主要作用是局域电子的平带与迁移电子的色散带之间的杂化。 这里的问题在于，由此产生的Kondo凝聚态仅出现在强耦合区域，在此区域内平均场理论的有效性值得怀疑。 因此，通过识别晶格效应与费米子的谱形状（由于与代表对称破缺的有序参数耦合所致），我们构建了具有强耦合的Kondo晶格的全息平均场理论。 对于平带谱，我们采用混合量子化；对于色散谱，我们在标准量子化中引入第二个费米子。 两个费米子与标量有序参数（代表Kondo凝聚）的耦合提供了两种谱的杂化，再现了Kondo晶格的主要特征以及强耦合系统的谱的模糊特性。 显示英文摘要

摘要： We first study a non-relativistic field theory model for the Kondo lattice by introducing the Kondo condensation, whose main effect is the hybridization of the flat band of the localized electron with dispersive one of the itinerant electron. The problem here is that the resulting Kondo condensation arises only in strong coupling where the validity of the mean field theory is questionable. Therefore, we build a holographic mean field theory of the Kondo lattice with strong coupling by identifying the effect of the lattice with the fermion's spectral shape due to the coupling with the order parameter representing the symmetry breaking. For the flat band spectrum we use the mixed quantization, and for the dispersive spectrum we intoduce the second fermion in standard quantization. The coupling of the two fermions with the scalar order representing the Kondo condensation provides the hybrization of the two spectrum, reproducing the main feature of the Kondo lattice together with the fuzzy character of the spectrum of the strongly coupled system.
