利用Yamada微扰论结合重整微扰方法来计算非对称Anderson模型,得到了局域电子占据数、重整化因子、重整化的局域能级以及重整化参数关于裸参数的展开式.计算了局域电子态密度和低温杂质电导,还计算了磁场对它们的影响,这些结果适用于从弱耦合到强耦合的整个耦合强度区域.由于在哈密顿量中已经将局域能级进行了初步重整,采用的重整微扰方法比Hewson的重整微扰方法更适合于研究非对称Anderson模型.
The asymmetric Anderson model is calculated by using the Yamada perturbation theory combined with the reforming perturbation method, and the local electron occupancy, renormalization factor, renormalization local energy level and renormalization parameters are obtained. . Calculated the local electronic density of states and the low temperature impurity conductance, also calculated the magnetic field on them, these results apply from the weak coupling to strong coupling of the entire coupling strength region.As the Hamiltonian has local energy level The preliminary reforming was carried out, and the reforming perturbation method adopted by Hewson was more suitable for studying the asymmetric Anderson model than Hewson’s reforming perturbation method.
