基于Anderson哈密顿量的平均场近似,我们计算了简单重费米子系统的准粒子能带结构。本研究的目的是研究Anderson哈密顿量的参数、f能级位置和杂化对准粒子带和费米面形状的影响。我们还计算了静态磁化率。
We present calculations of the quasiparticle band structure for simple heavy fermion systems, based on a mean-field approximation of the Anderson Hamiltonian. The aim of this investigation is to study the influence of the parameters of the Anderson Hamiltonian, position of thef-level and hybridization, on the quasiparticle bands and the form of the Fermi surface. We also calculate the static susceptibility.
