Full Self-Consistent Projection Operator Approach to Nonlocal Excitations in Solids
Yoshiro Kakehashi, Tetsuro Nakamura, Peter Fulde
A self-consistent projection operator method for single-particle excitations is developed. It describes the nonlocal correlations on the basis of a projection technique to the reta…
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…
Non local theory of excitations applied to the Hubbard model
Y. Kakehashi, T. Nakamura, P. Fulde
We propose a nonlocal theory of single-particle excitations. It is based on an off-diagonal effective medium and the projection operator method for treating the retarded Green func…
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…
Anomalous phase of MnP at very low field
T Yamazaki, Y Tabata, T Waki +3
Manganese phosphide MnP has been investigated for decades because of its rich magnetic phase diagram. It is well known that the MnP exhibits the ferromagnetic phase transition at $…
Non-conformally flat initial data for binary compact objects
Koji Uryu, Francois Limousin, John L. Friedman +2
A new method is described for constructing initial data for a binary neutron-star (BNS) system in quasi-equilibrium circular orbit. Two formulations for non-conformally flat data,…
