采用Anderson晶格哈密顿量,在超出平均场的理论框架下,讨论了重费密子超导电性问题。发现在Slave Boson场的长波长极限情况下,同类准粒子之间通过交换Slave Boson而产生的相互作用是吸引的,而只有第一类准粒子——准f电子对重费密子超导电性有贡献。Using the Anderson lattice, the heavy-fermion superconductivity is discussed. In the long wavelength limit of Slave boson field, the mutual interaction between the same type quasipar-ticles is attractive by one-Slave boson exchange and the heavy-fermion superconductivity is induced by the first type quasiparticles-quasi-f electrons only.
