Momentum Dependent Local-Ansatz with Hybrid Wavefunction from Weak to Strong Electron Correlations
M. Atiqur R. Patoary, Yoshiro Kakehashi
The variational theory of momentum dependent local-ansatz (MLA) has been generalized by introducing a hybrid (HB) wavefunction as a starting wavefunction, whose potential can flexi…
Momentum Dependent Local-Ansatz Wavefunction from Weak to Strong Electron Correlations
M. Atiqur R. Patoary, Sumal Chandra, Yoshiro Kakehashi
Momentum dependent local-ansatz (MLA) wavefunction describes accurately electron correlations from the weak to intermediate Coulomb interaction regimes. We point out that the MLA c…
Momentum Dependent Local-Ansatz Approach to Correlated Electron Systems: Non Half-Filled Case
M. Atiqur R. Patoary, Yoshiro Kakehashi
Momentum dependent local-ansatz wavefunction approach (MLA) to the correlated electron systems in solids has been further developed to solve best a self-consistent equation for var…
Ferromagnetism of transition metals and screened exchange interactions
Y. Kakehashi, M. Atiqur R. Patoary
We have investigated the magnetic properties of Fe, Co, and Ni at finite temperatures on the basis of the first-principles dynamical coherent potential approximation (CPA) in order…
First-Principles Dynamical Coherent-Potential Approximation Approach to the Ferromagnetism of Fe, Co, and Ni
Yoshiro Kakehashi, M. Atiqur R. Patoary
Magnetic properties of Fe, Co, and Ni at finite temperatures have been investigated on the basis of the first-principles dynamical CPA (Coherent Potential Approximation) combined w…
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…
