Embedding approach for dynamical mean field theory of strongly correlated heterostructures
H. Ishida, A. Liebsch
We present an embedding approach based on localized basis functions which permits an efficient application of the dynamical mean field theory (DMFT) to inhomogeneous correlated mat…
Multisite versus multiorbital Coulomb correlations studied within finite-temperature exact diagonalization dynamical mean-field theory
A. Liebsch, H. Ishida, J. Merino
The influence of short-range Coulomb correlations on the Mott transition in the single-band Hubbard model at half-filling is studied within cellular dynamical mean field theory for…
Jahn-Teller Inactivity and Magnetic Frustration in GeCoO Probed by Ultrasound Velocity Measurements
Tadataka Watanabe, Shigeo Hara, Shin-Ichi Ikeda
Ultrasound velocity measurements of cubic spinel GeCoO in single crystal were performed for the investigation of shear and compression moduli. The shear moduli in the param…
Single-Component Molecular Metals as Multiband π-d Systems
Hitoshi Seo, Shoji Ishibashi, Yoshinori Okano +4
Electronic states of single-component molecular metals M(tmdt)2 (M = Ni, Au) are studied theoretically. We construct an effective three-band Hubbard model for each material by nume…
