GW approximation with LSDA+U method and applications to NiO, MnO, and VO
S. Kobayashi, Y. Nohara, S. Yamamoto +1
A GW approximation (GWA) method named U+GWA is proposed, where we can start GWA with more localized wave functions obtained by the local spin-density approximation (LSDA)+U method.…
Electronic structure and effects of dynamical electron correlation in ferromagnetic bcc-Fe, fcc-Ni and antiferromagnetic NiO
Oki Miura, Takeo Fujiwara
LDA+DMFT method in the framework of the iterative perturbation theory (IPT) with full LDA Hamiltonian without mapping onto the effective Wannier orbitals. We then apply this LDA+DM…
Ill-Contact Effects of d-Orbital Channels in Nanometer-Scale Conductor
Hiroshi Shinaoka, Takeo Hoshi, Takeo Fujiwara
Electronic current in a nanometer-size rod is theoretically investigated by an eigen-channel decomposition method in nonequilibrium Green's function formalism. Physical properties,…
Shifted COCG method and its application to double orbital extended Hubbard model
Susumu Yamamoto, Tomohiro Sogabe, Takeo Hoshi +2
We explains the shifted COCG method which can solve a series of the linear equations generated by numbers of scaler shifts, without time consuming matrix-vector operations, except…
