First-Principles Theory of Momentum Dependent Local Ansatz Approach to Correlated Electron System
Sumal Chandra, Yoshiro Kakehashi
We have extended the momentum-dependent local-ansatz (MLA) wavefunction method to the first-principles version using the tight-binding LDA+U Hamiltonian for the description of corr…

First-Principles Momentum-Dependent Local Ansatz Wavefunction and Momentum Distribution Function Bands of Iron
Yoshiro Kakehashi, Sumal Chandra
We have developed a first-principles local ansatz wavefunction approach with momentum-dependent variational parameters on the basis of the tight-binding LDA+U Hamiltonian. The theo…
