Generalization of the iterative perturbation theory and metal-insulator transition in multi-orbital Hubbard bands
Takeo Fujiwara, Susumu Yamamoto, Yasushi Ishii
The iterative perturbation theory of the dynamical mean field theory is generalized to arbitrary electron occupation in case of multi-orbital Hubbard bands. We present numerical re…

Electronic Structure of Transition Metals Fe, Ni and Cu in the GW Approximation
Atsushi Yamasaki, Takeo Fujiwara
The quasiparticle band structures of 3d transition metals, ferromagnetic Fe, Ni and paramagnetic Cu, are calculated by the GW approximation. The width of occupied 3d valence band,…

Dynamical brittle fractures of nanocrystalline silicon using large-scale electronic structure calculations
Takeo Hoshi, Takeo Fujiwara
A hybrid scheme between large-scale electronic structure calculations is developed and applied to nanocrystalline silicon with more than 10 atoms. Dynamical fracture processes…
