首先通过s波散射近似将三维多通道共振能级模型转换成一维问题,然后利用玻色变换在算符水平上将其进一步转化为单通道Kondo模型,并在此基础上导出多通道共振能级模型的两个不动点哈密顿量.同时计算了模型的比热,讨论了系统的费密与非费密液体行为In this paper we have transformed the three-dimensional multichannel resonant-level model into one-dimensional model using ths s-wave scattering approximation, and then map it onto a single channel Kondo model at the operator level by use of a bosonization technique. The specific heat has been calculated and the Fermi and non-Fermi liquid behavior of the system have been discussed for two fixed point Hamiltonians.
