First-principles studies for structural transitions in ordered phase of cubic approximant Cd6Ca
Kazuki Nozawa, Yasushi Ishii
Recently low-temperature structural transition has been reported for complex cubic compounds Cd6M (M=Ca, Yb, Y, rare earth) and it is believed that the transition is due to orienta…

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…
