First-principles dynamical CPA to finite-temperature magnetism of transition metals (2009)
Kakehashi, Y., Tamashiro, T., Patoary, M. A. R., Nakamura, T.
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 electronic structure...
Evidence of Strong Electron Correlations in Gamma-Iron (2009)
Kakehashi, Y., Patoary, M. Atiqur R., Tamashiro, T.
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 which has recently...
Dynamical CPA and Tight-Binding LMTO Approach to Correlated Electron System (2008)
Kakehashi, Y., Shimabukuro, T., Tamashiro, T, Nakamura, T.
Dynamical Coherent-Potential Approximation (CPA) to correlated electrons has been extended to a system with realistic Hamiltonian which consists of the first-principles tight-binding Linear Muffintin...
