Quantitative Aspects of the Dynamical CPA in Harmonic Approximation
Toshihito Tamashiro, Shota Nohara, Keisuke Miyagi +1
Magnetic and electronic properties of the Hubbard model on the Bethe and fcc lattices in infinite dimensions have been investigated numerically on the basis of the dynamical cohere…
Dynamical coherent-potential approximation approach to excitation spectra in 3d transition metals
Y. Kakehashi, M. Atiqur R. Patoary, T. Tamashiro
First-principles dynamical CPA (Coherent-Potential Approximation) for electron correlations has been developed further by taking into account higher-order dynamical corrections wit…
First-principles dynamical CPA to finite-temperature magnetism of transition metals
Y. Kakehashi, T. Tamashiro, M. A. R. Patoary +1
We present here the first-principles dynamical CPA (coherent potential approximation) combined with the tight-binding LMTO LDA+U method towards quantitative calculations of the ele…
Evidence of Strong Electron Correlations in Gamma-Iron
Y. Kakehashi, M. Atiqur R. Patoary, T. Tamashiro
Single-particle excitation spectra of gamma-Fe in the paramagnetic state have been investigated by means of the first-principles dynamical coherent potential approximation theory w…
Dynamical CPA and Tight-Binding LMTO Approach to Correlated Electron System
Y. Kakehashi, T. Shimabukuro, T Tamashiro +1
Dynamical Coherent-Potential Approximation (CPA) to correlated electrons has been extended to a system with realistic Hamiltonian which consists of the first-principles tight-bindi…
