Local-Ansatz Approach with Momentum Dependent Variational Parameters to Correlated Electron Systems
Y. Kakehashi, T. Shimabukuro, C. Yasuda
A new wavefunction which improves the Gutzwiller-type local ansatz method has been proposed to describe the correlated electron system. The ground-state energy, double occupation n…

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…
