Strong coupling approach to actinide metals.
We present a strongly correlated approach to the electronic structure of actinide metals by deriving a low-energy Hamiltonian H[over] under the assumption that kinetic energy is small compared to Coulomb and spin-orbit interactions. The H[over]Pu for Pu metal is similar to the models used for Ce and other lanthanides but qualitatively different from the H[over] presented for the rest of the actinides. With H[over]Pu, we computed the photoemission spectrum and specific heat for alpha and delta-Pu and found good agreement with experiment.
