Abstract

Local Density Approximation together with Dynamical Mean-Field Theory is used to study the density of state for δ-Pu.The many-body Hamiltonian is obtained with the Hubbard model,and the Hubbard I approximation is used to solve the single-impurity problem.The calculations show the well-defined upper and lower Hubbard bands of the strongly correlated electron systems as well the quasiparticle kondo-like peak at the Fermi level.
