摘要: Abstract In a previous work an approximate Green function calculation of the Anderson lattice was performed, including hybridization between f- and conduction states in exact solution local Hamiltonian. Here we consider single impurity Cayley tree. Within this very simple method obtain Kondo peak density that decreases with temperature as expected.
